The CAOM2 validation code for TimeWCS expects that bounds and ranges are intervals. But intervals require (it appears) that Value1 < Value2. A valid 'exposure' in CAOM2 can have exptime=0. (BIAS for example) so that validate is not correct.
The validation checker needs to be updated.
NOTE: There should be some explanation of why delta_t == 0 was considered wrong, to begin with.
