Grads Developers! problem with options template?

[northrop grumman]

I have data sets which begin at 13z each day and
contain hourly data for 24 hours..
ie.,
1jan07.dat (contains data from 13z1jan - 12z2jan)
2jan07.dat
...
31jan07.dat

I have discovered that using the following lines in
the control file...

^%d1jan07.dat
options template

TDEF 744 13:00z1jan2007 1hr

produces a bigtime mistake.
It plot the first 11 hours of data correctly (ie.,
13z-23z) but when it gets to 00z on 2jan it plots 13z
on the 2nd. Basically it skips the last 13 hours of
each file.

When i use:

TDEF 744 00:00z1jan2007 1hr

it will plot the data correctly albeit with the wrong
times.

Is this a bug in GrADS?
