I need to set the time and date on my phone. Can't find the instructions that came with it.

SOURCE: How do I set the time and date?

You must be on the main phone on jack 01 to set time. You can determine if your phone is jack 01 by pressing PROGRAM and then pushing the number 6 on the dial pad. The phone will read the jack and extension number. When you have determined the jack 01 phone, do the following. 1. Push PROGRAM key 2. Dial "0" 3. Enter year (last 2 digits) 4. Enter month (01-12) 5. Enter day (01-31) 6. Enter day of week (Sun 0, Mon 1, Tue 2, Wed 3, Thu 4, Fri 5, Sat 6.) 7. Enter Hour (01-12) 8. Enter Minute (00-59) 9. Press 0 for AM 1 for PM 10. Press "AUTO DIAL/STORE" key 11. Push PROGRAM key to return to normal mode.

Just got this phone. It is indeed day/month/year. European style. NOT what we want for a phone in the states. Really annoyed with the fact there is not an option. Might be returning it.
