[idvusers] ISL script: output animation times

Hi IDV users,

Is it possible to use an ISL script to output the timestamps for each
timestep of an animation?  Eg. I have:

<movie imagedir="${islpath}" imagetemplate="MSLP_%time%_%count%.png"
file="${islpath}/MSLP.gif">

And I would like the '%time%' part for each timestep saved to a file.  I
know I could redirect from the standard output and then filter the results
to extract the timestamp, but I'm hoping there might be a straightforward
way to do this using the ISL script.

Thanks,

Paul
