If you have a free serial port there is always an old

Sure. We used to use rackmount GPS as time standards all the time for
scientific experiments in the 90s and 00s. For those, though, we had
to run antennas to the outside of the building.
If you have a spare serial port (easy with a DLV11-J) a Hayes
Chronograph can work, but those are hard to find and expensive now.
Easier to emulate that with a modern MCU and a DS1307 where the MCU
implements some parsable serial command scheme like the Chronograph
does.
