How to print the next crontab tasks to be executed?

Question

Is there some way to display a list of the approaching task executions? That is, translate this crontab:

# m h  dom mon dow   command
  * *  *   *   *     imapfilter
  4 20 *   *   Sun   fgit gc -- ~/*/ ~/.*/ ~/dev/*/

into this:

2012-04-12 14:40 imapfilter
2012-04-12 14:41 imapfilter
...
2012-04-15 20:03 imapfilter
2012-04-15 20:04 fgit gc -- ~/*/ ~/.*/ ~/dev/*/
2012-04-15 20:04 imapfilter
2012-04-15 20:05 imapfilter
...

It would be useful for verifying the saved schedules.
