Datetime.now as TimeSpan value?

Question

I need the current Datetime minus myDate1 in seconds.

DateTime myDate1 = new DateTime(1970, 1, 9, 0, 0, 00);
DateTime myDate2 = DateTime.Now;

TimeSpan myDateResult = new TimeSpan();

myDateResult = myDate2 - myDate1;

.
.
I tried different ways to calculate but to no effect.

TimeSpan mySpan = new TimeSpan(myDate2.Day, myDate2.Hour, myDate2.Minute, myDate2.Second);

.
The way it's calculated doesn't matter, the output should just be the difference these to values in seconds.

You don't need to do myDateResult = new TimeSpan(); - you don't have to have an initializing expression for every variable and/or you could make the initializer the following expression. – Brott

@user1559441, you have already calculated the difference in TimeSpan myDateResult, you may use TotalSeconds property to get the difference in seconds – Lindstrom

yeah, .TotalSeconds was the answer. thanks – Beginner

Answer 1

Your code is correct. You have the time difference as a TimeSpan value, so you only need to use the TotalSeconds property to get it as seconds:

DateTime myDate1 = new DateTime(1970, 1, 9, 0, 0, 00);
DateTime myDate2 = DateTime.Now;

TimeSpan myDateResult;

myDateResult = myDate2 - myDate1;

double seconds = myDateResult.TotalSeconds;

Code:

TimeSpan myDateResult = DateTime.Now.TimeOfDay;

please use code markup (add 4 spaces before the code line), i'd edit it myself but it's such a tiny change that the system won't let me. – Drummer

This should be the accepted answer, as it matches 100% the topic question. – Sauterne

Answer 3

Have you tried something like

DateTime.Now.Subtract(new DateTime(1970, 1, 9, 0, 0, 00)).TotalSeconds

DateTime.Subtract Method (DateTime)

TimeSpan.TotalSeconds Property

Answer 4

How about

myDateResult.TotalSeconds

Answer 5

you need to get .TotalSeconds property of your timespan :

DateTime myDate1 = new DateTime(2012, 8, 13, 0, 05, 00);
DateTime myDate2 = DateTime.Now;
TimeSpan myDateResult = new TimeSpan();
myDateResult = myDate2 - myDate1;
MessageBox.Show(myDateResult.TotalSeconds.ToString());

Answer 6

You can use Subtract method:

DateTime myDate1 = new DateTime(1970, 1, 9, 0, 0, 00);
DateTime myDate2 = DateTime.Now;
TimeSpan ts = myDate2.Subtract(myDate1);
MessageBox.Show(ts.TotalSeconds.ToString());

Answer 7

TimeSpan myDateResult;

myDateResult = DateTime.Now.Subtract(new DateTime(1970,1,9,0,0,00));
myDateResult.TotalSeconds.ToString();
