IIRC, if you do that the clock you will have problems at next daylight saving time change. Linux will assume the hw clock is local time, but the hw clock does not know about DST. If you boot Windows, it will detect that there has been a change of DST between last boot and this one and do the correction to the hw clock. Then you boot Linux and it is OK. There are a big number of failure scenarios: - what if you do not boot windows for some time? - what if you boot many windows instances from different partitions? - if you make the correction in Linux and than you boot Windows, it overcorrects, so you have to undo the second correction manually Basically timezone management in Windows is a total mess. Try the registry switch to let Windows run the hw clock in UTC mode, as suggested by someone else. Never tried if it really works. But at least it will leave your hw clock alone and Linux will never be affected. In this case the usual failure scenario is that someone sees a wrong time in the BIOS (UTC) and "corrects" it to the local time. :-) -- Roberto Ragusa mail at robertoragusa.it -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
