Daylight savings is part of the "timezone" setting, which in turn is part of the environment for every process. You can (in principle) set different timezone settings for each process you start by modifying the "TZ" variable.
This means that no reboot is necessary at all. If you have an application the system runs this application usually runs under a certain user-ID for this purpose. Set the "TZ" variable either in this users environment and then restart the application to make sure all processes are started with the new setting or change the machine-wide setting itself (you can use SMIT for this).
You may want to reboot your system anyway to make sure every running process has definitely this new setting in its environment but this is not required at all, it would be more of a "make 110% sure"-measure.
I hope this helps.
