operator + method
- Duration duration
Adds a duration
to this date.
Note that the curation is added as a value in seconds. Thus, adding a
Duration(days: 1)
will not necessary yield the same time tomorrow in all
cases (due to daylight saving time switches).
To change the value in terms of calendar units, see modify.
Implementation
Expression<DateTime> operator +(Duration duration) {
return _DependingOnDateTimeExpression(
// Date times are integers (unix timestamps), so we can do arithmetic on
// them directly.
forTimestamps: BaseInfixOperator(
this, '+', Variable<int>(duration.inSeconds),
precedence: Precedence.plusMinus),
forIsoString:
modify(DateTimeModifier.seconds(duration.inMilliseconds / 1000)),
);
