Javascript - How to check if current time is between two different times [duplicate]

Question

I am trying programmatically check if the current time for my web application is between two predefined times. I don't know how to get the current time and then set variables that store two predefined times. The pseudo code would look like this

if(currentTime < shiftStart && currentTime <shiftEnd)
{
   shift = 2
}

But how do I declare and setup the variables so the code works correctly.

Answer 1

var now = Date.now();
var time1 = //whatever time1 is
var time2 = //whatever time2 is

if (now > time1 && now < time2)
{
    alert("blah"):
}
