This is not really an idea, more of a bug report; however, I've been told this is how to further progress the issue:
AM/PM format currently used for scheduling changes – ambiguous, and it would appear inconstant regionally - is 12AM (Midnight), 1AM… 11AM, 12PM 1PM… 11PM, 12pm (Midnight).
Evidently, whoever designed/coded that did not understand what AM/PM means: clearly, 12 hours Post Meridian cannot occur at the meridian, i.e. noon.
24hr format is 00:00 to 24:00 (100% unambiguous and widely used in professional environments) and should be used instead of the current, flawed, AM/PM implementation in remedy.
