The UTC output time presented when applying the offset should be in the range of 0 to 10,000. Occurred on some computers

Question

I have the following code in a windows storage application using c #

birthDateTimePicker.Date = DateTime.Now;
if (birthDateTimePicker.Date == DateTime.MinValue)
     {
      no_date_lable.Visibility = Visibility.Collapsed;
      birthDateTimePicker.Visibility = Visibility.Collapsed;
      }

Note: this line is birthDateTimePicker.Date = DateTime.Now; for example, the user will actually be selected or will come from the server.

But I get an exception on this line:

if (dt_born_dt == DateTime.MinValue)

What is the reason for the thrown exception:

The UTC time provided when applying the offset should be between year 0 and 10000.

Indeed, I tested this on three computers, and I got an error in one of them.

I changed my system time zone to (UTC-08: 00) Pacific Time (USA and Canada) and did not receive this exception at all, and the codes worked correctly!

, , (UTC + 03: 30) !
