AixLib.Utilities.Time.Types.ZeroTime

# .AixLib.Utilities.Time.Types.ZeroTime

Use this to set the date corresponding to time = 0

## Information

Type for choosing how to set the reference time in AixLib.Utilities.Time.CalendarTime.

For example, `AixLib.Utilities.Time.Types.TimeReference.NY2016` means that if the Modelica built-in variable `time=0`, it is January 1, 2016, 0:00:00 local time.

When using `AixLib.Utilities.Time.Types.ZeroTime.UnixTimeStampGMT`, `time` is defined with respect to GMT. This is different from the use of `time` in the weather data reader AixLib.BoundaryConditions.WeatherData.ReaderTMY3, as the weather data reader assumes that `time` is expressed in local time.

#### Definition
