Data Time Selectors On Snooze Settings Do Not Respect Regional Settings
When regional settings are set to use 24 hour clock, snooze preferences still use the am/pm 12 hour clock system. Time settings in preferences should respect the system's regional settings.
This 24 hour clock issue seems to be popping up again, see here: http://feedback.airmailapp.com/forums/274948-airmail-mac-3-x/suggestions/7773597-24-hour-clock
Perhaps enforce a i18n process / standard library / components in development so that all features using a clock or calendar would by default support the regional settings from system preferences?
