timer - I want to run a R code at a specific time

Question

I want to run a R code at a specific time that I need. And after the process finished, I want to terminate the R session.

If a code is as below,

tm<-Sys.time()
write.table(tm,file='OUT.TXT', sep='');
quit(save = "no")

What should I do to run this code at "2012-04-18 17:25:40". I need your help. Thanks in advance.

It is easiest to use the Task Scheduler of Windows, or a cron job under Linux. There you can specify a command or program that should be run at a certain time you specify.
