When `DATE65.SYSTEM` is run (either directly or using the Open Apple-D shortcut in `EMAIL.SYSTEM`) it will:
- Show the current ProDOS date and time (or `---------- --:--` if it is not set.)
- Obtain the current UTC time using NTP server `pool.ntp.org`
- Display the dates when DST starts and ends in the current year.
- Examine today's date to determine if Daylight Saving Time is in effect or not.
- Convert the time to the correct local time.
- Show the new ProDOS date and time.
- Store the date and time in the reserved memory locations ProDOS uses for this information.
Note that if the system has a real-time clock (RTC) the date and time information obtained from `DATE65.SYSTEM` will be overwritten. Otherwise the date and time information remain constant until the next time `DATE65.SYSTEM` is run.
