Mad internal clock ??

Post by Nikola Smolensk » Wed, 16 Apr 1997 04:00:00



I have bare Amiga 1200 with no clock batteries. But, my internal clock managed
to set on 9th January 2007, and remained so even if Amiga is turned off for
days. Now, I am going to buy memory card recently, but I`m curious about how
such thing is possible?

Hello Nikola,

Well, there is no strange that Amiga sets some system date after power
up even without battery real-time clock. In fact the power up starting
procedure set system date by three ways. Firstly, system try  to  copy
one  from  real-time  chip  if it is available. Otherwise system looks
over the files on booting disk  for  search  maximal  value  of  "Last
Changed" date and uses one. If it is not possible for any reason (disk
is absent or non dos, etc) then date will  be  set  to  default  value
(1-Jan-78).  Note:  system  clock  and date value are set only in time
after power  up.  Ones  don't  changed  by  reset/reboot  but  may  be
corrected by "Time" prefs program or by command DATE or SETCLOCK.

Good luck!

No, for some time it was 1992 as it should be. Then I played with some
programs for setting time (on every boot), and...

Yes :)
