Hello, Guys, I hope you all will be fine. Well I am a facing an issue nowadays in my project that is I want to know How to subtract Datagridview Column Time and system current time in c#
for example, if I put time 3:20:02 in data grid view columns and after 15 minutes when I check data grid view so current time will be 3:35.02 I want to minus this time and wanna get value in another data grid view column like 00:15:00.

Solution 2

I would setup a variable to be of type System.DateTime then assign the datagridview cell value to it, then do something like variable = System.DateTime.Now - variable
then I would assign it to the new cell location with something like datagridview1.row.cell[1] = variable.ToString();

Solution 1

you can convert to timestamp

June 14, 2017 = 1497401466

June 13, 2017 = 1497315066

var resu = 1497401466 - 1497315066;
