And, if like me, you’re using Zapier … the Date formatter action outputs unix timestamps in just regular whole seconds. 

That caused me tons of errors and hours of troubleshooting. 

If you need to format a time input, use a Code by Zapier step and get an AI tool to help you prompt the python code to output it in milliseconds.
