When I enter 12:30 PM the value are converted to 0:30 AM.

When I enter 12:30 PM in a time field with the format (h:MM tt) the values are converted to 0:30 AM. Does anyone have any idea why this happens?

[Nesa Nurani]

Do you have any other scripts that could affect format in that field?

Try to test in on a new field.

This is pure logic.
There is no such thing as 12:30 PM, or 13:30 PM, or 12:30 AM.

You can't use 24:30 either.

@JR BoulayIt should still show as 12:30 pm if that's what he enters.

According to Wikipedia 12-hour clock - Wikipedia the minute after 12 noon is 12.01pm. So 12.30 am is just after midnight and 12.30 pm is just after noon. So that is a valid time. 12.59 pm is followed a minute later by 1 pm.

The 25th hour does not exist.

Copy-pasted from this Wikipedia page:

The 12-hour clock is a time convention in which the 24 hours of the day are divided into two periods: a.m. (from Latin ante meridiem, translating to "before midday") and p.m. (from Latin post meridiem, translating to "after midday"). Each period consists of 12 hours numbered: 12 (acting as 0), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11.

According to the tool it does. Not looking for logic. looking for a solution.

When I enter 12:30 PM I get 12:30 pm

"@JR BoulayIt should still show as 12:30 pm if that's what he enters."

So, you must remove the Date Format.

No date format. Time format of h:MM tt should accept 12:30 pm

I set up a time field, with format h:MM tt 

It accepts 12:30 pm fine. Creating and testing in Acrobat Pro 2022.003.20322.

I wonder if regional/system date settings make a difference? Mine are set to the default for UK.

Thanks so much, I have it set as time category
