FB FltLog for Windows supports 2 different time formats (Hour:Minute and Single Digit Decimal). It also uses different tables for automatic calculations. If you override the automatic calculations, actual minutes are rounded to the nearest 6 minutes for Decimal and 5 minutes for HM5. The following table shows how time is calculated for the decimal tables:
