Convert clock time to minutes

Question

How to convert the time 11:21:21 into total minutes?

Answer 1

How about something like

totalMins = (60 * hrs) + mins + (secs / 60)

Answer 2

Get the time as a TimeSpan value using the TimeOfDay method, then use the TotalMinutes method to get the time in minutes:

DateTime t = new DateTime(0, 0, 0, 11, 21, 21);
double minutes = t.TimeOfDay.TotalMinutes;

The minutes variable now contains 681.35. If you want the value as whole minutes use Math.Round or Math.Floor, depending on how you want it rounded:

int minutes = (int)Math.Floor(t.TimeOfDay.TotalMinutes);
