TotalMinutes; // use TotalMinutes, TotalSecibds, TotalMillisecons and etc var roundedMinutes = (minues - (minues%tf)); var roundedDate = dt. For example, if I get: 2017-05-01T16:16:35+05:00, in the DB I will store this data in 2 columns the first timestamp will have the value in UTC (2017-05-01T11:16:35), and the offset column will have the +5 timezone in minutes so -300 in minutes.
