When using "Schedule send" in Gmail, I prefer to specify the time in 24-hour format to avoid entering the time incorrectly around the hours of midnight and noon.
I noticed that when entering time in 24-hour format and then selecting the date, Gmail would automatically convert the time to 12-hour format however the choice of AM/PM seems arbitrary.
For example, 06:00 would be converted to 6:00 AM but 03:00 would be incorrectly converted to 3:00 PM!
How can I ensure that Gmail sets the correct time?
