The comparison is independent of whether the time is in UTC or in the local time zone.
var now = new DateTime.now(); var earlier = now.subtract(const Duration(seconds: 5)); assert(earlier.isBefore(now)); assert(!now.isBefore(now)); // This relation stays the same, even when changing timezones. assert(earlier.isBefore(now.toUtc())); assert(earlier.toUtc().isBefore(now)); assert(!now.toUtc().isBefore(now)); assert(!now.isBefore(now.toUtc()));
bool isBefore(DateTime other) { return _value < other._value; }
