set time format

[Ben Burford]

Hello Madhu,

Help from India.  Most excellent!  (I'm in Tokyo.)

I'm really glad to see that there is a simple format like this.  I'm also so
mewhat baffled that there was nothing about this in the GrADS Documentation
Index web pages under set t and set time commands.  I did check before I sen
t my email to the users list.  Oh well.

Thanks very much!

Ben
