duration-time | parse / format duration time | Date Time Utils library

Try timeInterval -- it measures time between two emissions.

To measure time between first START and next END:

I am not certain how 360 to 600 corresponds to the 6am to 10am, but that aside - AWS released a new tool in January - their AWS EC2 instance scheduler tool.

One thing they do is provide a dynamodb table that, among other things, lets you specify begin and end time schedules for when instances will be turned on and off.

They use a slightly different format, for example:

I saw this answer this morning (but had a busy day!) .. I created a jsfiddle for playing multiple sounds some time ago but when I re-read the question this evening, it seemed not quite enough to cover what you were trying to do.

I found that there is a library called MediaElement.js available; the source code is outlined extensively in this article and there is a demo also

Alternately there is very good (slightly lengthy!) article about designing a custom audio player by Rose (second name not given) on her website where there is also a demo

Best of all though, a fellow SO-er gives a wonderful answer to a similar question (about a year ago) and there is a jsfiddle provided in that answer (top pick i think..)

the code (hope there's room!):

Instead of:

To get the duration of the video you have to wait for the metadata portion of the video source to load (this can vary significantly depending on how the video has been encoded - ideally a 2-pass encode that relocates the MOOV atom to the beginning has been used so that can be extracted quickly).

By listening to the loadedmetadata event on the video object your code will know when it is safe to query that.

In the code below you will see I register the event handler using inline javascript (or could be in the document.onload) which in turn calls the function to extract the duration when the value is available. Any code that needs to know the value should then be run.

I've also added preload="auto" just for personal preference as it helps pre-buffer content in some browsers/devices, that's not needed for the event to work in most scenarios.
