Time Conversion from UTC to IST

Put:

private static TimeZoneInfo INDIAN_ZONE = TimeZoneInfo.FindSystemTimeZoneById("India Standard Time");

as a field.

Then, use:

DateTime indianTime =  TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, INDIAN_ZONE);

to get the time as needed.

public DataTable ChangeCreatedTime(ClientContext context, DataTable dt)
        {
            try
            {
                foreach (DataRow dr in dt.Rows)
                {
                    DateTime indianTime = TimeZoneInfo.ConvertTimeFromUtc(Convert.ToDateTime(dr["Created"].ToString()), INDIAN_ZONE);
                    dr["Created"] = indianTime.ToString();
                }
                dt.AcceptChanges();
            }
            catch (Exception ex)
            {
                WriteException(context, string.Empty, "Class File", "ChangeCreatedTime(ClientContext context, DataTable dt)", ex.Message);
            }
            return dt;
        }
