CallEventStartTimeStamp

Validations ASN.1 Parent Types

The timestamp gives the start of the call event.

The time is given in the local time of the Sender PMN (or Serving Network where this is not the Sender).  There must be a UTC Time Offset Code associated with the timestamp.

Note that local time is the local time at the location of the chargeable subscriber.  Where the location is not available, as in some call forwarding scenarios, this will be a notional ‘network local time’.
