Fire up function on certain time.

I have 3 times of a day in configuration file, and I want to start the same function on that time everyday by my windows service.
How can I accomplish that?
I read the times in string format, for now it is 24h clock format. Is that the best way to have it in config file?

Config file:
      <time1>7:00</time1>
      <time2>13:00</time2>
      <time3>19:00</time3>

The easiest way is to use a one second timer to see if a scheduled time has arrived or been slightly passed.

To avoid too much unneeded checking, upon service load or just after each scheduled event, set the timer interval to the time to wait before the next scheduled event, less a minute or so.  When that amount of time has elapsed, you can put the timer into one second intervals.

You may try just using the Windows Scheduler, which also allow mutilple scheduling. Use it to trigger your console app.

Though there's some limitations in it. The one bugged me most is the status checking mechanism of the Scheduler. You have to work it out instead of relying the Scheduler for proper logging.
