knk & Robert:
Thanks for the suggestion. It has been forwarded to our development team.
Please note that HealthFrame already accepts time entry that uses the 24-hr clock. (Robert, it does, however, require the colon separator, i.e. 13:00 works, but 1300 doesn't).
The problem is that HealthFrame is not currently looking at regional/locale settings and/or customizations, nor does it allow users to override the default hour display setting. (Please see the image below, where the data entry supports the 24-hr clock, but once you save, the time reverts to the 12-hr AM/PM clock).
Thanks,
Support Team
