DateTime.utc constructor
Constructs a DateTime instance specified in the UTC time zone.
final moonLanding = DateTime.utc(1969, 7, 20, 20, 18, 04);
When dealing with dates or historic events, preferably use UTC DateTimes, since they are unaffected by daylight-saving changes and are unaffected by the local timezone.
Implementation
DateTime.utc(int year,
[int month = 1,
int day = 1,
int hour = 0,
int minute = 0,
int second = 0,
int millisecond = 0,
int microsecond = 0])
: this._internal(year, month, day, hour, minute, second, millisecond,
microsecond, true);
