OK - that looks like a cron table entry. But how likely is it, given that you can translate a cron value to a datetime struct, that if will be exactly the same as DateTime.Now ? (It can always be considered as 'past' because cron table entries don't specify a year)

FWIW cron table entries are defined down to the minute level.

UPDATE: Also, an added wrinkle, a single cron table entry can effectively refer to multiple times....
