I met the problem months ago but left it unsolved. So I was glad to see
the solution however it didn't fit to my understanding of '-O.int' which,
I thought, affects only the RINEX header. I tried to decimate my files,
and now I'm double confused. It seems to be no problem!
I prepared 1s RINEX starting at second 22 and tried to decimate it
to 30s RINEX. The only option applied was '-O.dec 30' (no '-O.st',
no '-O.int'), and the result 30, 0, 30, 0, ... (not 22, 52, 22, 52, ...).
There were no problems with '-O.dec 5' too (25, 30, 35, ...).
I use teqc 2002Mar14 release, under both W2K and Linux works the
same. What your teqc version? Wasn't it corrected?
