Re: [ferret_users] Trouble with Ferret Crashing

[Roland Schweitzer <Roland.Schweitzer@xxxxxxxx>]

Hi,

I don't know if the units string is a problem for Ferret or not, but 
UDUNITS allows the time zone information to be included.

[rhs@stout /]$ udunits
You have: days since 1995-08-02  0:00:00 00:00
You want: hours since 1995-08-02  0:00:00 00:00
   <hours since 1995-08-02  0:00:00 00:00> = <days since 1995-08-02  
0:00:00 00:00>*24
   <hours since 1995-08-02  0:00:00 00:00> = <days since 1995-08-02  
0:00:00 00:00>/0.0416667
You have:

Seems like Ferret should allow the time zone info as well.
