toDateTime method
DateTime
toDateTime({
- TimestampUnit timestampUnit = TimestampUnit.milliseconds,
- NumberRoundType roundType = NumberRoundType.round,
Converts double to DateTime
In some languages, the timestamp takes the integer part as the second and the decimal part as the millisecond or other. This method should be used.
Such as:
1234567890.123456.toDateTime(timestampUnit: TimestampUnit.seconds)
=>DateTime(2009, 2, 14, 7, 31, 30, 123, 456)
1234567890123.456.toDateTime()
=>DateTime(2009, 2, 14, 7, 31, 30, 123, 456)
Implementation
DateTime toDateTime({
TimestampUnit timestampUnit = TimestampUnit.milliseconds,
NumberRoundType roundType = NumberRoundType.round,
}) {
var v = this;
if (timestampUnit == TimestampUnit.seconds) {
v = v * 1000 * 1000;
} else if (timestampUnit == TimestampUnit.milliseconds) {
v = v * 1000;
}
final time = v.roundToInt(roundType: roundType);
return DateTime.fromMicrosecondsSinceEpoch(time);
}
