ITelescopeV3UTCDate Property

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

Namespace:  ASCOM.DeviceInterface
Assembly:  ASCOM.DeviceInterfaces (in ASCOM.DeviceInterfaces.dll) Version: 3351c4f3fa64146a7efd5b51ed4591e32a0a5484
DateTime UTCDate { get; set; }

Property Value

Type: DateTime
PropertyNotImplementedExceptionIf UTCDate Write is not implemented.
InvalidValueExceptionIf an invalid DateTime is set.
InvalidOperationExceptionWhen UTCDate is read and the mount cannot provide this property itslef and a value has not yet be established by writing to the property.
NotConnectedExceptionIf the device is not connected
DriverExceptionAn error occurred that is not described by one of the more specific ASCOM exceptions. Include sufficient detail in the message text to enable the issue to be accurately diagnosed by someone other than yourself.

UTCDate Read must be implemented and must not throw a PropertyNotImplementedException.

UTCDate Write can throw a PropertyNotImplementedException.

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.
