Time Recording: Decimal time
Enable decimal time display
Caution: existing timestamps keep their original value if you switch the time format
from “regular” (“24 hours” or “AM/PM”, with base 60 minutes per hour) to “decimal” (base 100 minutes per hour), or vice versa.
The new time format is only applied when adding new timestamps or when updating existing timestamps.
Note this behaviour can lead to rounding offset with time total calculation (example see next section).
Mathematically speaking this affects all timestamps where the minutes portion (base 60 minutes) is not a multiple of 3.
Be careful when configuring “regular time” (base 60 minutes) with “decimal total” (base 100 minutes):
• Regular (base 60) minutes can have rounding deviation when converting to decimal (base 100) minutes.
• Sample: 00:20 (20 minutes) is equivalent to 33.3333 decimal minutes, which the app shows as “00.33”.
• However, three work units at 20 minutes summarise to exactly one hour, i.e. the app needs to show “1.00” in that case (instead of “0.99”).
→ Day totals are converted to decimal minutes independently from the individual work unit totals.
→ To avoid this see next section.
If you absolutely need to have your grand totals match the work unit totals then proceed with either of these options:
• Option A: Enter your punch times in decimal format, as shown in next section.
• Option B: Enable “Time rounding on «Punch now»” and round your punch times to 3 minutes
(why is that: this value converts to decimal time without fraction, i.e. 3 regular minutes is exactly 5 decimal minutes).
• Option C: Enable “Total rounding” with “Use for calculations & aggregrations” and “Apply to: Work unit, Day” as per “Mode 3 example”.
Note: with options A and B, existing punch entries remain unchanged and potentially still show total mismatch;
Option C immediately applies to all existing data.
Enable decimal time in the time selection dialog
This option is available when the “Time format” is set to “24 hours (decimal)”.
