Yes, a known problem with that release due to a change I put
in on 15 Dec. That version will decimate up to the first
millisecond reset in the rx time tag and then stop.
If you are starting with raw data, the workaround is to
translate with `+smtt` and then the decimation will work
fine. If you only have RINEX, then you have to backtrack
to an earlier version of teqc.
