Field of API REST worklog json == "started"

Question

Hi all,

I'm trying to post some worklogs and the json i have to use has a field like that:

"started": "2015-02-03T12:50:09.423+0000"

The problem is that i don't know what does the underline text mean.

Right now I use the format "yyyy-MM-dd'T'HH:mm:ss", the problem is that i dont know how to complete this field beacuse i don't know the meaning of .423+0000.

This is really relevant for the worklog POST json?

Thanks :)

I've solved for myself. I didn't know are the miliseconds and time zone.
