[gradsusr] How to extract / display the file time when using a template?

[Bob Kuligowski - NOAA Federal]

All,

     I'm using a template to create a loop of images for an entire day.  
I have the appropriate template settings in DSET, OPTIONS, and TDEF of 
my .ctl file; e.g.,

> DSET 
> ^/data/smcd2/rainfall/yli/ABI/Evaluation/srcNewFixCof/outputNew/2018/022/RRR_GRABI2018022%h2%n2.nc
> OPTIONS yrev template
> DTYPE netcdf
> UNDEF  -99
> UNPACK scale_factor add_offset
> TITLE Operational GOES-R QPE
> XDEF 5424 LINEAR 1 1
> YDEF 5424 LINEAR 1 1
> ZDEF 1 LEVELS 1000
> TDEF 96 LINEAR 00:00Z22JAN2018 15mn
> VARS 1
> RRQPE=>rr_v5y   1 y,x   RRQPE
> ENDVARS
     Everything displays just fine, BUT...I would like to be able to 
display the hour and minute of each file in the image along with the 
associated data field.  Is there a GrADS variable that will either give 
me the value of TDEF associated with the that I can parse for display, 
or at least the value of %h2 and %n2 associated with the time period 
currently being displayed so I can create a time string to append to the 
image display?  Thanks!

Cheers,
