  • The difference is already a TimeSpan you can use TotalMinutes or Hours etc. endDate - startDate = TimeSpan. https://learn.microsoft.com/en-us/dotnet/api/system.datetimeoffset.op_subtraction?view=net-5.0 – Felipe Ramos Aug 29 '21 at 05:32
  • In the future, please include what code you’ve tried. – Jeremy Caney Aug 30 '21 at 19:51

It sounds like you're looking for DateTimeOffset.TimeOfDay:

The time interval of the current date that has elapsed since midnight.

var dto1 = DateTimeOffset.Parse("2021-08-28T13:30:00+00:00");
var dto2 = DateTimeOffset.Parse("2021-08-30T13:45:00+00:00");
var diff = dto2.TimeOfDay.Subtract(dto1.TimeOfDay);

Convert the resulting TimeSpan to whatever units you want.
