The smallest value you can put on a check recent only is one day. Often this is too long. For example, I run a batch process that slightly modifies the footers in every page on the website. If a do a check before that, I should not need to recheck every document afterwards, and certainly not recheck them every document on the website every time I do any check in the next 24 hours.
It would be nice to have allow that field to read:
10 mins
2 hours
4 days
with the units defaulting to days.
If you want to get really fancy also allow an absolute timestamp in ISO form:
2008-08-05 14:59
