- What's the use ?
- ----------------
-
- A program for all ATARI ST -useres whose computers have no hardware-clock.
-
-
-
- Installation
- ------------
-
- Copy D_T_E.PRG (or, if you prefer the german version, D_T.PRG) into the
- AUTO-folder on your boot-drive.
-
-
- What does it do ?
- -----------------
-
- There are (at least) two clocks in your ST, one can be accessed via GEMDOS
- the other via XBIOS.
-
- The GEMDOS-clock is (almost) pure software. At system start (reset) it is set
- to midnight and the date of the TOS-version.
- The XBIOS accesses either the 'intelligent' keyboard (260, 520, 1040,...) or
- battery powered hardware clock (MEGA ST[E], ...) (If you ST has such a
- hardware-clock, you don't need this program). The keyboard-processor clock
- keeps running until the power is switched off.
-
- So, after a reset the XBIOS-time stands a good chance of being correct.
-
-
- First a definition of three conditions :
- A) Is the current Date equal to the TOS-version date ?
- B) Is the day 0 ?
- C) Is the month 0 ?
-
- If at least one of these conditions (A-C) is fullfilled, the date is called
- invalid (B and C were only defined because my keyboard-processor always
- sets the date to 00.00.28 after power up).
-
-
- 1. First the GEMDOS-date is checked. If it is valid the program
- displays date and time and then exits.
-
- 2. If the GEMDOS-date is invalid, the XBIOS-date is being tested.
- If the XBIOS-date is valid, GEMDOS time and date are set to XBIOS
- time and date, a message, time and date is displayed, and then
- the programm exits.
-
- 3. If the XBIOS-date is invalid the program asks you to enter date and time.
-
- You can make the program ask for time and date by holding down the RIGHT
- SHIFT key at program start.
-
- First , you are asked to enter the current date, format MMDDYY.
- That means two figues for the month, two figues for the day and two
- figues for the year.
-
- EXAMPLES:
- Feb. 3. 1991 => 020391
- Dec. 25. 1992 => 122592
-
- After that you're asked the enter the current time, format HHMM.
- You've guessed it, two figures for the hour and two figures for the
- minutes.
-
- EXAMPLES:
- 5 past 9am => 0905
- 25 past 2pm => 1425
- 10 past midnight => 0010
-
-
- The input can be cleared with ESC, BACKSPACE and DELETE work as usual.
