Call a javascript function at a specific time of day

Question

for example i want to call a js function at 10.00.00.00 am how can i do?

Answer 1

My solution for running a script at a specific time, btw no error checking for negative timeout.

//year, month 0-11, date, hour, min (can add ,sec,msec)
var eta_ms = new Date(2015, 0, 21, 17, 0).getTime() - Date.now();
var timeout = setTimeout(function(){}, eta_ms);
