I concur. It appears to be a bug in cron, or Cygwin's version of cron.
The following fails to work correctly for me:
1. Create the following crontab entry:
* * * * * /usr/bin/date >> /tmp/date.txt
2. Start cron as a service and wait one minute. Cron adds a line
to /tmp/date.txt.
3. Using Windows's "Adjust Date/Time" applet, set the date to the previous
day.
4. Wait one minute, and cron adds another line to /tmp/date.txt.
5. Using Windows's "Adjust Date/Time" applet, set the date to the current
day.
6. Wait one (or more) minute, and cron does NOT add another line to /tmp/date.txt.
Cron should resume updating /tmp/date.txt.
If I stop the cron service and restart it, then cron resumes updating /tmp/date.txt.
