By Bill Sanderson:
I’ve dug into this bug, as follows:
Users in locales where the default clock is a 24 hour format will find that they cannot set scheduled scan times in the afternoon.
This can be worked around by selecting a time format which uses 12 hour format rather than 24 hour.
This is on the Time tab, and a working format is: h:mm:ss tt
A non-working format is: any of the choices with a CAPITAL H at the beginning.
This isn’t my discovery, it was posted by others here, but I’ve done some testing:
1) I set my language to English (United Kingdom) afternoon settings failed (default time is 24 hour.) Reset time to 12 hour,and afternoon settings worked.
2) I set my language to English (United States) Default time setting is 12 hour. Scheduling scans in the afternoon works fine. Change just the time settings to a 24 hour choice, and you can no longer set up a scheduled scanin the afternoon.
This bug appears to me to be new in build 614.
