I'm need to run a function at specific times of the day (e.g. 0010, 0610, 1210, 1810). My current approach uses a ticker for _ = range time.Tick(21600 * time.Second) and I manually launch the program at one of these intervals (e.g 1210). This is obviously sub-optimal.

What's the best solution to this? I thought of running the ticker every 60 seconds and then checking to see if the time matched one of the intervals, but that doesn't seem very elegant.

What you're really after here is a scheduler, so your options are:

  • Limit your program to just what you want done at each interval, but use an existing scheduler to do the scheduling - a simple example would be to use a cron job (or for Windows, Task Scheduler) to launch your program according to the required schedule

  • Turn your program into a scheduler in its own right, which invokes the required function correctly on schedule. Your program would then ideally need to run as a daemon (service, on Windows), or be launched once and left running all the time somehow

    I removed the tick function and now use crontab commands to run the compiled executable at specific intervals. This makes the program simpler and should increase reliability. – surfearth Nov 15 '15 at 04:09
