Overview
Every HR admin who has ever managed time in a large, multi-country enterprise knows the complex challenges that comes with a single sentence in an email: “The collective bargaining agreement has been updated. Changes effective June 1.”
What follows is a familiar scramble. You need to change an overtime threshold in your Time Recording Profile. But the profile is shared across thousands of employees. So, you clone it, rename it, update the threshold in the new clone, then mass-update Job Information records so employees are switched over on exactly the right date. Then someone asks: “What about the weekly timesheet that spans May 31 and June 1?” The Time Sheet is split and requires to be handled as part of payroll run.
I've heard this story from customers across industries — manufacturing in Germany, healthcare in Australia, retail in France. The pain is universal. The root cause? Time Valuations were not adapting to these changes themselves. A configuration object that calculates when people work, how much they earn, and whether rules are met — couldn't change over time without an admin/partner's intervention.
That's why we designed Effective-Dated Time Valuation solution.
At its core, the feature is versatile: instead of changing a Time Valuation and affecting all history, or cloning a profile to create a parallel universe, admins can now add a new time slice to an individual Time Valuation with a future effective date. The existing version stays as is for all past calculations. The new time slice is activated on the date it's meant to be effective. The hassle of creating clone of time recording profile, mass updating of Job Information and dual maintenance of time recording profile is completely avoided.
And this isn't just about overtime thresholds. The use cases span the full breadth of what Time Valuations do today:
- Daily and weekly overtime rate changes – when a Time Administrator updates a multiplier from 1.5× to 2.0×
- Night shift premium windows – when a shift agreement narrows the qualifying hours from 20:00 to 06:00 to 22:00 to 05:00
- Break deduction rules – when a works council agreement changes the minimum break duration that counts against working time
- Non-working day premium rates – when legislation mandates public holiday pay at 2.5× instead of 2.0×
- Business rule conditions – when FTE eligibility for overtime expands from FTE <= 0.8 to FTE = 1.0
- Health and safety alerts – when the threshold for a daily working-time warning moves from 10 hours to 12 hours
- Late-arrival detection – when HR policy increases the tolerance window from 5 minutes to 15 minutes and adjusts the alert trigger from 2 to 3 occurrences per month
- Multi-country configurations – when Germany and France share a time recording profile, but each has a rule change on a different date
And critically, the retroactive corrections. If an Overtime threshold was set incorrectly at 9 hours when it should have been 8, and this is discovered 15 months later via the Time Valuation Trace tool, the admin corrects the effective-dated slice for January 1, 2025. The system triggers a retroactive recalculation across all 15 months, for all the affected employees.
Configuration
The configuration model is intentional in its simplicity. Let me take you through the various scenarios of versioning.
Versioning of Time Valuation
When there is a policy change, the admin navigates to the specific Time Valuation that needs to change — say, the `SPLIT_OT_10` Aggregate & Split Time Valuation that calculates daily overtime. Instead of editing the existing record (which would rewrite history), you add a new version with the effective date of the change.
For example:
Version 1 (original): Threshold = 8 hours, valid from the Time Valuation's creation date (01/01/1900)
Version 2 (new): Threshold = 10 hours, effective June 1, 2026
The old version is untouched. The chain of downstream Time Valuations — the ones consuming the output of `SPLIT_OT_10` — needs no reconfiguration. They simply receive whatever the versioned Time Valuation produces on any given calculation date.
This is the key insight of the design: you version at the point of change, not at the top of the chain. Downstream Time Valuations that are not affected by the rule change don't need a new version. Only the Time Valuation where the logic actually differs gets updated.
Handling Cross-Boundary Timesheets
One of the most technically interesting aspects of this feature is how the time valuation engine handles a timesheet that spans a version boundary. Take a weekly timesheet for June 28–July 4, where the overtime threshold changes on July 1.
The system resolves the effective Time Valuation version per processing day when Time Valuation method is Valuate Per Day or Valuate Upto Today:
June 28, 29, 30 → Version 1 (threshold = 8 hours)
July 1, 2, 3, 4 → Version 2 (threshold = 10 hours)
The result is that the correct overtime is calculated for each day, even within a single submission.
In the Weekly Time Sheet, if the Time Valuation method is Valuate Whole Sheet or Period, the behavior changes.
The system resolves the effective Time Valuation version with Time Sheet or Period end date which in this case is July 4th. The value of end date of the Time Sheet is considered and calculated with the values as follows:
June 28, 29, 30, July 1, 2, 3, 4 → Version 2 (threshold = 10 hours)
Retroactive Recalculation
When an error is discovered in a system governing payroll, effective dating enables a clean correction path.
The admin updates the effective version of the Time Valuation that contained the error (for instance, correcting an overtime threshold from 9 hours to 8 hours effective January 1, 2025). This triggers a retroactive Time Valuation recalculation for the entire affected period. The Trace tool (Summary of Valuations) provides confirmation of the correction before a payroll rerun is triggered. No individual employee records need updating. No profile changes required. A single administrative action propagates correctly across all affected periods and employees.
Attendance Quota and Effective-Dated Variables
It's worth noting how this capability intersects with Attendance Quota — a feature that allows employees to request pre-approval for overtime, work from home, or higher duties. When an Attendance Quota Type is configured, the system automatically creates Time Valuation Global Variable Values for Attendance Quota Type “Overtime” (e.g., `DOES_QUOTA_EXIST_OVERTIME`, `TIME_SEGMENTS_OVERTIME`, `WEEKDAY_OVERTIME`, `WORKINGDAY_OVERTIME`). These variables are inherently effective-dated — they reflect the valid period of a specific Attendance Quota request.
This means effective dating operates at two levels: at the configuration level (the Time Valuation itself changing over time) and at the runtime variable level (employee-specific quota windows informing time valuation logic dynamically). Together, they allow a single Attendance Quota Type to serve many employees across different time periods without configuration duplication.
The system handles Time Sheets that straddle a boundary — if a weekly timesheet runs June 28 through July 4 and the Overtime threshold changes on July 1, the engine automatically applies version 1 to June 28–30 and version 2 to July 1–4, within a single timesheet for Time Valuations having valuation method as Valuate Per Day and Valuate Upto Today.
For Attendance Quota with variable `QUOTA_LIMIT_OVERTIME`, the Time Valuation method used is generally Valuate Whole Sheet or Period. Hence, the end date of the Time Sheet is considered for the calculation of the entire Time Sheet. June 28 – July 4 will use the version 2 values for all calculations.
Results of Time Valuation
Trace
The Time Valuation Trace tool (Summary of Valuations) already provides a window into how time is calculated. Now, it provides the effective dated slices as well.
When a weekly timesheet spans a version boundary (e.g., June 28–July 4 with a July 1 OT change), the trace should clearly show two timelines: the calculation using version 1 for June 28–30 and the calculation using version 2 for July 1–4. For each processing day under a Valuate Per Day method, the trace explicitly states which threshold value was applied.
Payroll auditors, works council representatives, and HR business partners routinely need to explain to employees why their overtime was calculated differently within a single paycheck period. A trace that surfaces the effective-dated timeline removes ambiguity and reduces disputes.
Time Recording Profile Visualization
The broader vision is a visualization layer within the Time Recording Profile that lets admins and HR compare configuration states across time.
With an “As of Date” control, an admin should be able to pull up the Time Valuation configuration as it existed on any date in history — and compare it to how it looks today, or how it will look after a future version activates. The visualization shows inputs, outputs, thresholds, and routing logic side by side across versions.
Limitations
- Time Valuation method and type cannot be changed. This will raise an error that they have to be same for all effective slices.
- Create Time Record doesn't support creating more than 1 time slice.
- Inactive slices are not allowed and each Time Valuation will always have an effective date 01 Jan 1900 by default.
- Attendance Quota type cannot be changed in time slices.
Best Practices for Effective-dated Time Valuation
- Effective-dated Time Valuation should be used for policy and legal changes where minor changes in threshold, change in input or output time type group, raise messages, factor, etc. This should not be used to change the complete semantic like changing period results from monthly to weekly or visa versa.
- As Effective-dated Time Valuation uses the end date for all Time Sheet and Period related calculations. Hence, it is important to ensure that you are getting the correct value at boundary conditions. For ex: For a Time Sheet period from June 28, 29, 30, July 1, 2, 3, 4, the calculation will be based on the July 4th time slice which is active. Kindly ensure you this expectation is communicated to stake holders as the results will change for the last week and will not be the same as other weeks when time slice changes on July 1.

Conclusion
Effective-Dated Time Valuation is one of those features that's hard to explain but immediately understood by anyone who has spent time in the trenches of payroll-adjacent HR configuration.
It doesn't change what Time Valuation calculates. It changes when configuration changes take effect, how they're managed over time, and what happens when the world doesn't cooperate with clean period boundaries.
For the admin who has been cloning profiles every time a collective agreement changes — this removes that entirely. It also now helps in adding new features with an effective date and don't require to worry about the recalculation that possibly runs for 1 yr or so.
