Better check for time axes that chosen -B interval is compatible with chosen DATE|CLOCK formats
|Target version:||Candidate for next minor release|
The is currently no internal check that makes sure the user does not specify an annotation interval for a time axis (say in years) that is incompatible with one of the DATE or CLOCK formats the user also selects. The example that triggered this was a FORMAT_DATE_MAP setting of u (Week) but giving annotation interval in integer years. No warning, but annotations were not as expected. To implement such a check would be difficult but perhaps a matrix could be developed where we could store allowable combinations.
