Why my export report is different from some reports?

Why my export report is different from some reports?

The unit of the report is indicated at the end of it is in a hundredth: N.B. The figures on this report are in hundredths (1/100) rather than in minutes (1/60)

1. Reports in sixtieth (HH: mm)

In timesheets, and in the majority if timesheet reports, the unit used is the sixtieth.
Examples:
1h30min = 01:30
1h45min = 01:45
1h15min = 01:15
To calculate hundredths in minutes: take the digits after the decimal point x 60 (min).
Example: 1.8 = 1h + (0.8 x 60min) = 1h + 48min
Reports that use the sixtieth unit: 
  1. Batch timesheet & timesheet report
  2. Individual & individual summary in batch
  3. Overtime 
  4. Punches per employee
  5. Modified punches per Employee
  6. Timebank
  7. Banks summary
  8. Real hours summary
  9. Hours worked summary (Reports-Costs)

2. Reports in hundredths (HH.mm)

In the pay exportation report, the unit used is the hundredth.
Exemples:
1h30min = 1.5h
1h45min = 1.75h
1h15min = 1.25h
To calculate sixtieths in hundredths: take the minutes and divide them by 60 (min). 
Example: 1h + 36 min / 60 = 1.6h
Reports that use the hundredth unit:
  1. Export report
  2. Pay summary
  3. Daily summary
  4. Inter-Division
  5. Training
