I would have thought the prime meridian was the spacial component for UTC? I thought the full long time zone name was Etc/UTC and UTC as the abbreviation. Regardless, in all the libraries I've used, you can use Etc/UTC or UTC in exactly the same way you would use something like Australia/Sydney or AEST. So perhaps, from a pedantic standpoint, it is not a time zone, but for all intent and purpose in this discussion, I feel that point is irrelevant.
