To find out how much time is between two DateTime objects useĭifference, which returns a Duration object: final difference = berlinWallFell.difference(moonLanding) You can write: final now = DateTime.now() įinal later = now.add(const Duration(hours: 36)) To create a DateTime object based on another.įor example, to find the point in time that is 36 hours after now, Use the add and subtract methods with a Duration object Print(dDay.isAtSameMomentAs(localDay)) // true Print(berlinWallFell.isBefore(moonLanding)) // false print(berlinWallFell.isAfter(moonLanding)) // true The DateTime class contains methods for comparing DateTimesĬhronologically, such as isAfter, isBefore, and isAtSameMomentAs. EETīetween UTC and the time zone of a DateTime objectĬall timeZoneOffset. Use timeZoneName to get an abbreviated name of the time zoneįor the DateTime object. To get the equivalent date/time value specified in the other time zone. Use isUtc to determine whether a DateTime object is based in UTC. Unless explicitly created in the UTC time zone. Working with UTC and local timeĪ DateTime object is in the local time zone That is, the constants january and monday are both 1.

You can use these constants to improve code readability: final berlinWallFell = DateTime.utc(1989, DateTime.november, 9) Īssert(berlinWallFell.month = DateTime.november) Īssert(berlinWallFell.weekday = DateTime.thursday) ĭay and month values begin at 1, and the week starts on Monday. The DateTime class provides a constant for each day and month The individual units of a DateTime object. Once created, neither the value nor the time zone Or in the local time zone of the current computer Note: hours are specified between 0 and 23,įinal berlinWallFell = DateTime.utc(1989, 11, 9) įinal moonLanding = DateTime.parse(' 20:18:04Z') // 8:18pmĪ DateTime object is anchored either in the UTC time zone
