Pretty much what the subject says:

Text( Now(),DateTimeFormat.ShortTime,"en-GB")

Returns the time in ShortTime24 format (23:45 rather than 11:45 PM) when the locale is "en-GB". This is the case when the locale is auto-detected or specified (as shown). However, DateTimeFormat.ShortTime works as expected with "en-US". Using DateTimeFormat.LongTime with "en-GB" has the same issue except it returns LongTime24 (which is something, I guess!)

Hi @philip_dt,
can you please try this formula:

// 12‑hour for any user

Text( Now(), "h:mm AM/PM" )

// 12‑hour but parse for GB local .

Text( Now(), "[$-en-GB]h:mm AM/PM" )

you can get more info about showing dates and time in canvas apps from this article !!!

Hi @philip_dt,

This is expected behavior in Power Apps.

For en-GB, the regional standard uses the 24-hour clock, so:

DateTimeFormat.ShortTime → 23:45

DateTimeFormat.LongTime → 23:45:00

If you need 12-hour format with AM/PM, don’t rely on DateTimeFormat. Use an explicit format string:

Text(Now(), "[$-en-GB]hh:mm AM/PM")

This ensures consistent 12-hour formatting regardless of locale or environment.

I hope this works for you!

n Power Apps, the DateTimeFormat.ShortTime enumeration is designed to be locale-aware, meaning it follows the regional standards of the specified locale. For the "en-GB" (United Kingdom) locale, the standard time representation is the 24-hour clock (e.g., 23:45), which is why you see it returning what appears to be ShortTime24.

In contrast, the "en-US" (United States) locale defaults to a 12-hour clock with an AM/PM designator (e.g., 11:45 PM).

Huh. Well, I never knew! Only worked in en-GB my whole life.

However, that being the case, the "docs" at https://learn.microsoft.com/en-us/power-platform/power-fx/reference/function-text are poor. There is no mention of "regional standards" on the page and the section on "Predefined date/time formats" doesn't even mention locale.

In that section, ShortTime enumeration is simply described as "Hour (12-hour clock), minutes, and AM/PM designation." Apparently that's not what it does at all!

Does ShortTime24 in fact override the regional standard of the specified locale and force 24-hour clock?
