In a dual boot system Ubuntu time is set to UTC by default. The display time on Linux desktop is calculated based on the UTC (GMT) time of BIOS. Vista uses BIOS' time as local time, thus lead to incorrect reading for LT. To solve this issue use a favorite editor tool to edit /etc/default/rcS and change UTC=yes to UTC=no so that BIOS' time is set to local time rather than UTC.

It's automatic, maybe the Active flag of the partition do the trick. While Grub try to take over MBR and the snippiest points the rest of boot sequence to the destinated partition, to restore MBR for Vista is fairly quick and easy. Take out your DVD installation disk, boot from it and choose system mantenance. In command line interface, type: bootrec / fixboot bootrec / fixmbr That's it. Now you can restart your PC, take out installation DVD and it should boot directly to Vista.
