Re: [ferret_users] Trouble with Ferret Crashing

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

HI John,
I'm not sure that the time units in your file would cause Ferret to 
stop. (The message you see means that the routine CONFINE_AXIS has run 
into an error code other than the ones it expects and knows how to issue 
error messages for.  There is not another log file with more info -- the 
answer is to ask the developers what to do.)

If the problem is indeed with the time origin given in the file, you can 
change it when you open the file, with a SET AXIS/T0 command

yes? set data datasetname.nc
yes? set axis/t0="1995-08-02 00:00:00"  TIME

or, get the name of the time axis from the name of a variable.  As Jon 
says, you don't need to specify the hours, minutes, seconds if they are 
all 00 anyway

yes? set axis/t0="1995-08-02"  `air_u,return-taxis`
