Does asking IRIG B signal for time synchronisation automatically fixes the time resolution of 10 mS ? What does B in IRIG B stand for ?

IRIG-B is simply the designation for the version of time code. There are also IRIG-A and IRIG-C through IRIG-H. IRIG Standard 200-98 describes the various codes. IRIG-A and IRIG-G have count intervals of 1 ms and 0.1 ms respectively.

The IRIG-B timecode itself indeed only has 10 ms resolution, but that's never been an issue, since all IRIG-B decoders are equipped with a crystal-based real-time clock that's synchronized to the time code. This allows the time code receiver to have usually better than 1 us time resolution under all conditions.

IF you need any further ralyabilkity on the tiem sync, You may be able to scope your IRIG-B timecode generator to sync with the timecode yourself, if avaiable.
