subtract method

PreciseDateTime subtract(
  1. Duration duration
)

Returns a new PreciseDateTime instance with duration subtracted from this PreciseDateTime.

final today = PreciseDateTime.now();
final fiftyDaysAgo = today.subtract(const Duration(days: 50));

Notice that the duration being added is actually 50 * 24 * 60 * 60 seconds. If the resulting PreciseDateTime has a different daylight saving offset than this PreciseDateTime, then the result won't have the same time-of-day as this, and may not even hit the calendar date 50 days later.

Be careful when working with dates in local time.

Implementation

PreciseDateTime subtract(Duration duration) =>
    PreciseDateTime(val.subtract(duration));
