|
<p> ClockFix is a background-only application for
|
|
System 7 or later to use in Mini vMac to
|
|
keep the emulated clock accurate. As described in the
|
|
<a href="../../hardware.html#rtc">Real Time Clock</a>
|
|
documentation, the clock of the emulated computer may
|
|
become inaccurate when the emulation is paused, such
|
|
as when switching to another application and then
|
|
back to Mini vMac. One work around is to
|
|
open the Alarm Clock desk accessory. ClockFix is
|
|
an alternative that may use less time and space.
|
|
It also has the advantage of not appearing in
|
|
the list of running applications in the
|
|
Application menu, and the “Hide Others”
|
|
command of that menu won’t disable it. </p>
|
|
|
|
<p> To use ClockFix, place it in the “Startup Items”
|
|
folder inside the “System Folder” and restart. </p>
|
|
|
|
<p> About once a second (by the emulated computer’s time),
|
|
ClockFix calls “ReadDateTime” which
|
|
reloads the copy of time kept in memory from
|
|
the Real Time Clock. </p>
|
|
|
|
<p> ClockFix does use some time and space, so it should not
|
|
be used if an inaccurate clock doesn’t matter. You can
|
|
use it if you want the modification dates of files
|
|
you are editing to be accurate. You would not
|
|
generally need to use it for games. </p>
|
|
|
|
<p> Warning: according to Apple’s Technical Note TN1126,
|
|
“All applications and Background Only Applications
|
|
should have a memory partition set to at least 64K. This ensures
|
|
there is always enough room for the system and extensions to
|
|
work in the application’s heap.” The memory partition
|
|
for ClockFix is set to 10K, and it seems to work, but it
|
|
is possible there could be a problem depending on what
|
|
extensions are installed. If so you can increase the
|
|
memory partition of ClockFix. </p>
|
|
|
|
<p> ClockFix should not be used on a real Macintosh. For
|
|
one thing, it would be pointless. For another, a
|
|
part of the Macintosh Family Hardware Reference seems
|
|
to raise the possibility that ClockFix might drain
|
|
the clock’s battery faster. </p>
|
|
|
|
<p> If you use <a href="../autquit7/index.html">AutQuit7</a>, then
|
|
ClockFix is not needed, since AutQuit7 optionally
|
|
includes all the functionality of ClockFix. </p>
