cps_recv accepts possibly wildly invalid times and causes daq crashes
See FRS 16874 (https://services.ligo-la.caltech.edu/FRS/show_bug.cgi?id=16874)
Invalid times are being sent by h1oaf1 when there is some glitch/corruption on the dolphin that gives it its time. This then gets passed onto the daqd via the cps_recv process. The daqd sees a time jump and aborts.
There is some hints that it is a large time jump.
