I looked at mine: GMT Delta read from XPRAM: 0 minutes, DST: on I don't knnow how to change the DST to off Now, I moved the S18hwclockfirst.sh & S50hwclock.sh back into my rcS process and also the K25hwclock.sh in rc6 for now.. BUT and then typed # hwclock --localtime --systohc and the times worked and stayed even when putting the pb to sleep... UNTIL... I rebooted into OS X and the times were off the -8 gmt (PST) and then booted back into Linux to find out that the times were back into GMT. I think I keep getting my self deeper and deeper into the rabbit's hole going round and round with the dual boot. LOL I have tried using the hwclock daemon and not using it but each one had its own set of issues. I am very perplexed. -adam -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
