Answer 2

+3 A:

EDIT:

DateTime day180 = Date.Now.AddDays(-180);

It's important to put it into a separate variable otherwise the value will be lost.

Pretty sure he doesn't want to know what the date was 180 **months** ago. ;)

technophile 2010-02-23 16:08:47

He wants days back, not months back.

Ugh, nice catch. Fast fingers doing stupid things.

Answer 4

+17 A:

DateTime oneEightyAgo = DateTime.Today.AddDays(-180);

I would use DateTime.Today as opposed to DateTime.Now because Today is just the date with 00:00 as the time, and now is the moment in time down to the millisecond

Many thanks for that

This is probably the most insightful answer I've seen yet on SO - cheers

Thanks, the whole DateTime.Today and DateTime.Now is a sticking point for me, especially in code review. It's the whole concept of doing it the right way as opposed to a solution that happens to work (Programming by Coincidence - The Pragmatic Programmer)

Answer 5

+2 A:

DateTime oneEightyAgo = DateTime.Now.ToUniversalTime().AddDays(-180);

Its best to record UTC...

Brian Leahy 2010-02-23 16:21:23

There is also DateTime.UtcNow for that.
