TelescopeUTCDate Property
The UTC date/time of the telescope's internal clock

Namespace: ASCOM.DriverAccess
Assembly: ASCOM.DriverAccess (in ASCOM.DriverAccess.dll) Version: (
public DateTime UTCDate { get; set; }

Property Value

Type: DateTime


The driver must calculate this from the system clock if the telescope has no accessible source of UTC time. In this case, the property must not be writeable (this would change the system clock!) and will instead raise an error. However, it is permitted to change the telescope's internal UTC clock if it is being used for this property. This allows clients to adjust the telescope's UTC clock as needed for accuracy. Reading the property will raise an error if the value has never been set or is otherwise unavailable.
