Timer Jobs in SharePoint 2010
Microsoft SharePoint Server 2010 is rich in features. When properly configured SharePoint can support collaboration, manage shared documents, define workflows, schedule tasks, etc.
Another key feature of SharePoint Server 2010 is a Timer Job. A timer job runs in a specific Windows service for SharePoint Server and performs infrastructure tasks for the Timer service, such as clearing the timer job history and recycling the Timer service; and tasks for Web applications, such as sending e-mail alerts. A timer job contains a definition of the service to run and specifies how frequently the service is started. The SharePoint 2010 Timer service (SPTimerv4) runs timer jobs.
The most significant change you will see in SharePoint Server 2010 Timer Job is that 21 news Timer Jobs have been added here. If for an ordinary SharePoint 2007 application we had 39 Timer’s Job, then we have 60 Jobs for SharePoint 2010. The recently added Timer Jobs include the following:

The SharePoint 2010 Timer service (SPTimerv4) is based on the Gregorian calendar for scheduling. For every job that you schedule, you specify when the timer job will run, specified in a 24-hour time format. You must specify the time in local time instead of as an offset from Coordinated Universal Time (UTC). The time is stored in that format. Daily, weekly, and monthly schedules also include a window of execution. The timer job will select a random time within this interval to start executing the job on each applicable server. Timer Job is appropriate for high-load jobs that run on multiple servers on the farm. Running this kind of job on all the servers at the same time might place an unreasonable load on the farm. Timer job schedules can be specified by using Windows PowerShell.
