An overnight shift needs two dates. A statement needs a period. A review needs an agreed boundary. None of these can safely be supplied by the word “yesterday.”
Write the overnight interval first
Start with the local date and time at each end in your own private notes. “Monday 22:00 to Tuesday 06:00” describes an eight-hour clock interval when no clock change occurs. “22:00 to 06:00” alone does not say whether the end is the next morning or a different day. The workbench requires an explicit same-day or next-day selection rather than silently assuming an overnight shift.
Its calculation is deliberately limited to a single interval no longer than 24 hours. It is not a date-aware timekeeping system. Do not use it for a daylight-saving transition, a change of time zone, multiple days, on-call rules or a combination of shifts. Preserve the actual timestamps and ask how the employer’s record represents that case.
Do not assign the whole interval to a pay period yourself
Suppose a fictional interval begins on the last date shown in one statement period and ends after midnight. That raises a question about allocation; it does not answer it. A schedule grouping, a payroll grouping and a personal calendar grouping may be different views. Ask which period contains the relevant entries instead of deciding from the calendar layout.
The Department of Labor’s general recordkeeping sheet lists the start of the workweek, daily and weekly hours, payment date and period covered as separate record fields. Those fields make useful labels for a reconciliation sheet. The fact sheet does not identify this employer’s boundary for your assignment.
Three boundaries to label
- Event boundary
- The start and end of the particular interval you are asking about, including the change of date
- Comparison boundary
- The exact span being compared across the plan, time record and statement. Do not compare one day with a whole period total
- Processing boundary
- The period or correction cycle identified by the responsible workplace contact. Ask for it if it is unknown
This is an editorial vocabulary, not official payroll terminology. Use the labels your workplace actually uses in any submitted request.
Fictional case: an eight-hour interval split across two dates
When the clock itself changes
A wall clock can repeat or skip a time during a seasonal change. Subtracting two displayed clock readings can then produce a different result from elapsed time. The workbench does not try to resolve that ambiguity. Keep the date, zone and any timestamp offset available in the permitted source, and ask the responsible team which record they used.
Even without a clock change, two devices may show different zones. Preserve the label shown by the original record. Do not silently convert it and present the conversion as original evidence. For ordinary notation issues, continue to decimal hours and hours:minutes.
