Convert To Milliseconds

Third party integrations Node-RED

Hi all.

I have a time that is in the format of
2019-08-09T05:27:03.648773+00:100:
How do you convert that to milliseconds? Is there a simple function or do I have to pull it appart and get out the indervidual hours etc?

Don’t understand what you mean. Millisecond is a duration unit and what you have is a date (wich is not a duration).
Which milliseconds do you want :

  • milliseconds ellapsed since a specific date to the date you have => timestamp is something to consider
  • milliseconds of the date you have ? You can just cut the text you don’t need in your date !

I need to convert the date and time to milliseconds since 1971 as in I think its called UNIX epoch.

You’ll need to cut your input as : 2019-08-09T05:27:03.648773 because the part “+00:100:” is not recognised.
To cut, use a function node with :

msg.payload = msg.payload.split("+", 1)
return msg;

And then it will be readable by the date/time formatter node.
In output format of this node you will have to setup “XX” to get as output a millisecond timestamp.

This is as i would do it, maybe not the best solution :wink:
