The Client is adjusted to regional settings. So if you change to 24 hour format VisualCron will use that.
To view the jobs in 24 hour format this works.
I was wondering if there is a way to change the time formatting in a triggered time event when you view or set it. Like when setting up a custom time trigger. Is there a way to set this to 24 hour time?
Changing the system settings did change much of the VC interface to 24 hour time, just not the add job -> trigger -> time trigger -> custom -> Hour(tab)
