Well I don’t suppose you are looking for or likely to find a standard single clock source generator, on frame by frame second by second time code locked to both on the domestic market.
I, for one, was surprised at how many SMPTE timing options were available in RB.
It's video handling is lacking, but you can use various SMPTE time options including drop frame etc. to try syncing it to other sources.
It allows syncing to external SMPTE as well as Auto Sync Chase (or whatever for syncing to another clock starting point).
I haven't stressed tested it recently, but when I first found it I remember testing it with various frame rates.
Of course if things get off time, another option is to use RB to simply make a 32 second audio 31.5 seconds (or whatever) to help it line up.
Lots of ways to approach it.
