I think this is about the observation summary in the rinex file.

What dou you suggest?

Best regards,

Completely unrelated.  The notice about the GNSS_nav_time() would only be pertinent
when outputting Beidou RINEX nav, and then only if the Beidou navigation messages
rolled from one week to the next.  I doubt you are creating those and reading them
in GAMIT/GLOBK.  (The mentioned case for GNSS_nav_time() -- Beidou navigation messages
from Leica MDB at week rollover -- is one that I don't have data to test.)

If you do a `teqc -O.sum . <filename>` on one of the RINEX obs files being created
by teqc and used in GAMIT/GLOBK, what do you get back?
