Hi @Crios29 :
Date calculation in Excel is a form of sorting dates into a series, increasing by 1 every day, so that the date can be stored as a serial number that can be used for calculation. By default, the serial number of January 1, 1900 is 1, and the serial number of January 2, 1900 is 2, and the serial number of January 1, 2008 is 39448. This is because it is 39,448 days from January 1, 1900.So, using this principle, you can restore these floating-point numbers to date and time.
Text(
DateAdd(
Date(1900,1,1),
Int(Thisitem.'Rpt Sent'*24*60),Minutes),
DateTimeFormat.LongDateTime24)
Or
Text(
DateAdd(
Date(1900,1,1),
Int(Value(Thisitem.'Rpt Sent')*24*60),Minutes),
DateTimeFormat.LongDateTime24)
Best Regards,
