Crazy Date and Time

Has anybody else had this happen to them?

I noticed this morning that my clock in the menu bar was wrong. I'm not sure how long it has been like that, but I know that it has been accurate in the past.

I moused up to the time, clicked, and selected Open Date and Time. To my surprise, iDVD2 opened instead of the Date and Time! I tried this repeatedly, and the same thing happened every time.

I had to go into my system preferences to open the date and time settings. Fortunately, this didn't open iDVD2, and I was able to edit the date and time. I found that the date had switched to December 31, 1969 and the hour was 4:10pm, rather than 7:20am!

I'm not sure what, when, or why this happened. Has anybody else had the same experience? When I updated to iDVD2 and OS 10.1.1, I had no problems at all. The clock seems to be fine now.

My computer specs are as follows:

DP800 G4
OS 10.1.1
60GB hard drive

similar problem

ive had a similar problem, only mine is that if whenever i switch between os 9 and os x, it messes the time and date of both of them up. very annoying. theres also a mouse bug in os x. maybe its because im using a non apple usb mouse, but i like to keep my setting on fastest. however, when i reboot into os x, the bar setting is on fastest, however the actual mouse speed is average, where it should be if the setting was right in the middle. whats even worse is that if i move the bar back down, i can get my mouse to go REALLY slow, but i cant fix the problem unless i put the setting on a lower speed, reboot and/or relog in, and then up the setting again. real pain...

all in all, these are my only two real problems with os x, and they are minor at that, so im pretty happy.

Lost Time & Mouse problem...

The lost time issue is generally caused by a bad battery on the motherboard that holds the time information while the machine isn't plugged in.

Generally, these batteries should hold the clock time for a year or so without any power supplied to the machine. However, the latest revision of the iMac had a problem where the battery would run out prematurely if the machine was left unplugged from power. They fixed the iMac issue with a firmware update a couple months ago.

Maybe your G4 has a similar issue? Do you unplug the machine or turn off power on the power strip when it's not in use?

Of course, clock time is also lost if you reset the PRAM.

As for the mouse issue, I've read about this elsewhere. One report suggests that it will reset itself if you unplug and replug the mouse into the USB report.

Hope this helps.

10 Minutes from Disneyland
i have a PBG4 400 and my clock goes wacky all the time, it's rather anoying...and it happens almostonce a day. my iMac doesn't do it (233w/ OS X.1) and neither does my QuickSilver 867, so, my guess is a battery conflict or something with the firmware cause my 4400 did that for a week once, then i upgraded the firmware and it worked just fine ever sence. oh well, just one of the small issues we have to put up with occationaly...
