Hi,

you already made a string out of it so can't use DateTime members on that anymore.

You can make it like:

		var now = DateTime.Now;
		now.AddMinutes(13);
		now.ToString("yyyy-MM-dd HH:mm:ss,fff");

So first create a variable that holds the first time, then perform adding minutes and when you have that result write it out as a formatted string.

It is, tested it before I wrote it down.

Well, if you already made it a string then before you can add minutes to it you'll have to transform it back to a valid DateTime instance, call AddMinutes on it and then perform a ToString on it again with the formatting.

Then it seems you have a string and that you try to add minutes to a string. Always work with the native type as long as you can. Transform the value to a string when you are done will all native operations and you are about to show the value to the user, write the value to a file or whatever...
