Automatically restart service at a specific time

[MrAlyn89]

Hello everyone,

I have setup a proxy server with AD authentication and have set webaccess limitation to function only during office hours. The problem is that this schedule does't always work and i have to restart from time to time the squidGuard service. This solves the problem, but i was wondering if it is possible to set squidGuard or any other service, to automatically restart at a specific time?
If it is possible, could anyone post an example?

Thx
