Hi, I have a API that receives dates with values like this; 2017-12-28T23:53:58.176Z, Im trying to use custom formats:
yyyy-mm-ddThh:mm:ss.sssZ
yyyy-mm-ddThh:mm:ss.fffZ
yyyy-mm-dd hh:mm:ss.sssZ
But none of then work, please your help.
Thank you,
Rodrigo F.
I ran into this exact problem while using the Youtube Data API (same format you’re looking for). I ended up stringing together a couple formats to make it work. For testing, I wanted the current date/time plus five seconds entered in format you’re looking for. Here is a screen cap of what I did for that use case:

Hey, long shot but I’m hoping you can help!
I’ve followed your recipe to a t, but I’m still getting an API error that it cannot parse the data.
I’m trying to send the dates I capture to act as dynamic values for my API GET call.
Unfortunately, no matter what I do it doesn’t seem to work.
Do you have any suggestions?
You need
yyyymmdd”T”HHMMss”Z”
But the time zone must not be users time zone - set it to UTC
Z MEANS ZULU
which is UTC time zone
And your HHMM needs to be capitals
And your T and Z need quote marks
Hey! Thanks for the response. I discovered that the date being passed through was only yyyy-mm-dd, so everything is fixed!
