Rca led tv shows military time is there a way to change it to regular time?

Question edited for clarity and toss in some CAPS.

Military Time is 24 hour Time, 00:00 to 23:99! It sounds like actually want 12 hour time, 12 hours of A.M. and 12 hours of P.M.

You just ask :>D

Say "Change to 24-Hour clock" or use the Alexa app.

1. Open the Alexa app .
2. Select Devices .
3. Go to Echo & Alexa, or to All Devices.
4. Select your Echo Dot with clock device. This opens device settings.
5. Under General, select LED Display.
6. Turn 24-Hour Clock on or off.

Change the Time Format on Your Echo Dot with clock

..

Just press some buttons on your Audio Player and Recorder.

If your stated 'make model (what it is)', it would help a bit!!

Or you could Google

make mode manual

or

make model change from military time.

You know that Google knows everything right?

Possible fix above.

you have it set on 24 hour time instead of 12 hour time
it will change over at midnight to military time as that is when the 24 hour period ( military time ) starts

Have a look at the manual

The manual is available at Bose.com and page 17-18 shows the detail.

Press and hold Clock Set, and then press On/Off to switch between AM/PM (12 HR) or military (24 HR) formats

This is controlled by hardwired switch (12/24) OR digitally during menu setup sequence.

With the sytem off, hold down the Alarm Setup button and the On/Off button to switch between 12 hour (AM/PM) and 24 hour (Military) time. If you need the manual go to
