Questions tagged [timespan]

An elapsed measurement of time between two events or during which an event, program or a function continues. Also known as a timedelta or a duration.

A timespan is an elapsed measurement of time between two events or during which an event, program or a function continues.

It is also known as a timedelta or a duration in many programming languages.

  • For most intervals of time, this is calculated by:

    EndTime - StartTime

    This works especially well for half-open intervals that are used by time-only ranges, or date+time ranges.

  • However, be careful with date-only ranges. Typically these are expressed using fully-closed intervals, such as Jan 1 to Jan 2 to represent two days. This is calculated by:

    EndDate - StartDate + 1

Is there a more elegant way of removing seconds from a TimeSpan?

Assuming I have a TimeSpan that is equal to 07:10:30, I can use the following code to strip the seconds from it: myTimeSpan = new TimeSpan(myTimeSpan.Hours, myTimeSpan.Minutes, 0) Is this appropriate, or is there a more elegant way to achieve this?
