isAtSameMomentAs method

bool isAtSameMomentAs (DateTime other)

Returns true if this occurs at the same moment as other.

The comparison is independent of whether the time is in UTC or in the local time zone.

var now = new DateTime.now();
var later = now.add(const Duration(seconds: 5));
assert(!later.isAtSameMomentAs(now));
assert(now.isAtSameMomentAs(now));

// This relation stays the same, even when changing timezones.
assert(!later.isAtSameMomentAs(now.toUtc()));
assert(!later.toUtc().isAtSameMomentAs(now));

assert(now.toUtc().isAtSameMomentAs(now));
assert(now.isAtSameMomentAs(now.toUtc()));

Implementation 

bool isAtSameMomentAs(DateTime other) {
  return _value == other._value;
}
