jquery convertion from string to time

I have a system in development which records various times of the day in the following format: 06:53:22 or 19:23:58 as examples.

Can anyone tell me if it is possible to convert this string into javascript construct which I can use to compare times of the day?

You can parse the time with this:

function timeToSeconds(time) {
    time = time.split(/:/);
    return time[0] * 3600 + time[1] * 60 + time[2];
}

It returns a number of seconds since 00:00:00, so you can compare the results easily:

timeToSeconds('06:53:22') < timeToSeconds('19:23:58')

of course you can do it, but before you should parse this string. date = new Date(year, month, day, hours, minutes, seconds, milliseconds) - we creaeted new object. After we can use date.getTime() date.getFullYear ..

var startTime = "19:23:58";
var endTime = "06:53:22";

var startDate = new Date("1/1/1900 " + startTime);
var endDate = new Date("1/1/1900 " + endTime);

if (startDate > endDate)
  alert("invalid time range");
else
  alert("valid time range");

js is smart enough to figure it out :)
