Set time and date?

If your phone is similar to my AT&T DECT 6.0 cordless phone system, press Menu/Select with the phone in standby. (If your base has a corded handset, you can do this on either the base or a handset. The button is below the LCD screen on the handset. It's in the middle of the buttons below the LCD screen on my system's base.) Use the Up/Down arrow keys to navigate to Settings. (If you use the base, Up and Down are on different sides of the Menu key.) Press Menu/Select. Use the arrow keys to navigate to set date and time. Press Menu/Select. Type in the date using two digits for month, day, and year. Press Menu/Select. Today's date will be 06 21 18. Type in the time (12-hour clock) with two digits each for the hour and minutes. Use the Up/Down arrows to select AM or PM. Press Menu/Select to save. You should hear a confirmation tone. Press Exit multiple times to exit the menu system on the base. Press Off from a handset.

I hope this helps. Please add a comment with your phone system's model number if you'd like me to search for a manual. The manual for a system like mine, the CL84215, is here: https://cdn-media-att.vtp-media.com/products/CL/CL8XXX5/CL84XX5_CIB_i4.0_20170412.pdf .

Robert, this info is out of the manual from link below courtesy of vtech Canada support.
If you subscribe to caller ID service, the day, month and time are set automatically with each incoming call. You can also set the date and time manually. Press MENU when the handset is not in use. Scroll to select >SETTINGS, then press SELECT. Scroll to select >SET DATE/TIME, then press SELECT. Use the dialing keys (0-9) to enter the month, date and year, then press SELECT. Use the dialing keys (0-9) to enter the hour and minute. Press or to choose AM or PM, or press 2 for AM or 7 for PM. Press select to save.

Press the up or down triangles to reach DATE/TIME. Press MENU/SELECT.
Use the keypad to set the year. Press MENU/SELECT.
Use the keypad to set the date. Press MENU/SELECT,
Use the keypad to set the time. Press the up or down triangles to select a.m. or p.m. Press MENU/SELECT
The screen displays STORED and you'll hear a confirmation beep.

The date and time are set when you receive the first call after plugging in your phone.I have the owners manual if you need more help.

I found it on the manual, it was in programming section!

Date/Time
NOTE: Time set on handset will be transferred to the base unit automatically.
1. Make sure your phone is OFF (not in talk mode).
2. Press the menu button to go to the main menu and use cid/vol (3or4) button to scroll to Date/Time.
3. Press menu button to enter the menu. Year 2006 shows in the display.
4. Use the touch-tone pad to enter the last two digits of the current year (range: 00 to 99).
5. Press menu button to save the year setting and proceed to date setting.
6. Date 01/01 shows in the display. Use the touch-tone pad to enter two digits for current month and day respectively.
7. Press menu button to save the month/date setting and proceed to time setting.
8. Time 12:01p shows in the display. Use the touch-tone pad to enter four digits for current time and use cid/vol (3or4) button to toggle between "p" (pm) and "a" (am).
9. Press menu button to save the setting. Saved shows in the display.
NOTE: If you subscribe to Caller ID service, the current date/time is set automatically when you receive your first CID record and will override manually set date/time.

This is due to the base unit losing power and needs the clock resetting.
The handsets retain their clocks under battery power so this is a little misleading.

To reset the base unit clock:
- press the OK key
- press the 'down' arrow twice until "DATE/TIME" is displayed.
- press the OK key again, this will display the year. Enter the correct year on the handset numeric keypad and then press OK. (Only the last two digits of the year need to be entered).
- The date is then displayed in MM/YY format, enter the correct date on the handset numeric keypad and then press OK.
- The time is then displayed, enter rhe correct time on the handset numeric keypad and press OK.
- The handset then beeps and displays "SAVED".
- Press the "C" button and replace the handset on the base unit.

The base unit should now stop flashing "CL".

I'm almost positive there's nothing wrong with your phone "ssandra". You set the day/time/year etc. on the base (answering machine) separately from the handset . . . you press a series of buttons. I've done it several times, but now after a move I can't remember how you do it, and I can't find the instructions I had. That's actually why I was on this forum (looking for the instructions). Since you posted your question last year, this probably can't help you now. But I thought I'd answer anyway . . .

If you are trying to set the date and time for the answering machine the buttons to do that with are on the right side of the main phone base.
