I try to type something in an pm but nothing shows up?

On that type of clock, (I have similar), you just move the hours forward 12 hours. There is an indicator that shows AM and PM. You will see it change as you scroll past 12:00.

I did mine this morning.

am does not show only Pm

You mean time is only coming in AM. The clocks are usually 12-Hour display. So it should automatically turn to PM once you go past 12 hours. I am assuming you have the manual and you are correct it does not show separate setup for AM or PM. You simply keep increasing the hour until it passes 12:00 and it should go to 1pm. Similarly once you go past 00 hours (midnight) it will switch to AM.
Hope this helps.
Manual for reference (won't help you if you already have it)

You might try a new AA battery.
Some guy wrote in this week and said he bought 6 timers and all the batteries were bad except 1.

Some timers, like Woods TD1300, and others have the 12 hour or 24 hour option.
You press and hold Time button to choose 12 hour or 24 hour
But GE 15117 manual says nothing about this option.

GE 15117 timer is same timer as Woods 59403
Several folks have written in past couple weeks about the Woods 59403 timer skipping over functions.
The best I can guess is your timer is malfunctioning like the other people's timers.

Woods 59403 manual is identical to GE manual, and says nothing about 12 hour 24 hour option either

I test timers for programming and wiring difficulties.
Yesterday 3 timers arrived here, and 1 didn't work.
I took it apart and tested the electronics, and something went bad.
When these timers don't work, you get your money back or throw them away.

Check to make sure nothing is blocking the drive opening all the way if something is the drive will auto close to not damage the drive if that is not the case then check all the controllers to make sure non are pressing any buttons when you try. and try connecting your xbox 360 to xbox live to make sure it is fully updated if it is not any of that then it sounds like it is a hardware issue and you will need to call

Where you can try typing "try closes" or something along thos lines.

Make sure you have media player 11
If you can, the best test is to try your player with another PC, to see if you still have the problem. This localises whether the problem is with the PC (most likely the USB) or the player. See the link below (search on "connection problems") for a lot more troubleshooting on this.
Download recovery tool off creative's website.
go to my computer > click on hardware tab >
click on device manager button > in the is next screen on the bottom should have>>universal serial bus controllers
(write these down just in case it cant find them)
right click on them and uninstall
reboot let windows reinstall them
Also told Microsoft hotfix causes this problem try uninstalling the last hotfix
If that doesn't fix it try the USB cable
