DateTime and DateTimeOffset are two date and time types in the .NET Framework.
DateTime:D ateTime is a struct that represents the date and time. It contains information such as year, month, day, hour, minute, second, and millisecond. The value of the DateTime type is based on the local time zone, i.e., it represents the date and time relative to the local time zone. The DateTime type is suitable for scenarios where time zones do not need to be considered, such as recording the time when an event occurred.
DateTimeOffset:D ateTimeOffset is also a struct that represents dates and times. In addition to containing information such as year, month, day, hour, minute, second, and milliseconds, it also contains an offset that represents the offset relative to Coordinated Universal Time (UTC). The DateTimeOffset type is suitable for scenarios where time zones need to be considered, such as time calculation and storage across time zones.
Distinguish:
- The value of the DateTime type is based on the local time zone, while the value of the DateTimeOffset type is based on UTC and offset.
- The DateTime type does not accurately represent time across time zones, while the DateTimeOffset type can accurately represent time across time zones.
- The DateTime type may be affected by changes in the local time zone when performing time calculations, while the DateTimeOffset type is not affected by changes in the local time zone.
In practical applications, choose whether to use DateTime or DateTimeOffset according to specific needs. If you need to consider time zones, especially time calculation and storage across time zones, the DateTimeOffset type is recommended.
