Sure. Biggest hurdle will be if you mean their most recent run or an older run. The former is a simple 'dsjob' query, the latter will need intact logs and more involved scripting.

dsjob -lognewest would give you the latest log details, from which you can find the date of the last run.
-logsum, -logdetail can also be used for the same purpose.
Impossible doesn't mean 'it is not possible' actually means... 'NOBODY HAS DONE IT SO FAR'
Or even easier might be to (off the top of my head) use "dsjob -jobinfo" which would include that information in a format that might be a little easier to parse out.
