SetDate by Rob Braun - avoid year 2020 Bug in System 6, 7, 8

There's a problem with old Macs in the year 2020 as many of them can't show 2020.
For the year 2020 bug please look here too:

68k & PPC Macs can't show the year 2020 in the time & date extension (below system 9).
First I searched in 68kMLA Forum and found this:
(you have to sign in to read)
So I knew, that there's a solution: SetDate by Rob Brown (2011), but some members there tell about freezing problems with their Macs and SetDate-1.1.
I tried SetDate-1.1.cpt_.hqx on my Macintosh SE/30 (System 7.5.5) and it worked without freeze.

I then tried SetDate-1.1 on my PowerBook 2400c (G3 PPC processor card) but the PowerBook froze and I had to reset it.
As Rob Braun‘s homeserver was down:
I did a search in and found a backup of Rob's website:
There I found 3 versions of SetDate!
I tried the oldest version (SetDate.cpt_.hqx) and it worked on my PowerBook 2400c. So I tested more of my PowerBooks:
PB 170
PB 180c
PB 540c
PB Duo 270c
PB Duo 280c
PB Duo 2300c (PPC)
PB 5300 ce (PPC)
PB 3400c (PPC)
PB 2400c (PPC)
and sytems:
System 7.1.1
System 7.5.5
System 7.6.1
MacOS 8.1
MacOS 8.6
All worked with SetDate.cpt_.hqx, the oldest version.
I never tried SetDate 1.0.

Sorry for my late answer. I have no time to translate the PRAM battery pdf into english now.
If somebody wants to do it, I'll send him the Word.doc file.

I wonder if this software will help with this Year 2038 problem when the time comes? (Wikipedia)

@MikeatOS9: Thanks for the PDF. Much appreciated. It could be placed up here at the MG too, if you want to make a page for it.

Fortunately, my LC III uses those "1/2 AA" cells, which are still easy to come by!

As for this, I would think I'll set the old computer's clock to an earlier date, but not the current one.

Vremya is a good app, thanks for mentioning it.
The other problem are the pram batteries, which are mostly dead in old devices and are usually no longer available.

I had no idea! I have been using Vremya to set my system clock, and while this does require an internet connection, it does so without having to go into Date & Time, which I haven't done since before the new year...
