How are dates stored in HubSpot's backend


I'm in the process of creating a Zapier Zap to post messages in Slack and want to add a filter for dates.

The example deal from HubSpot, in Zapier, displays dates and timestamps as a set of numbers (i.e. 1530641714391).

Has anyone been able to get around this so you can filter on dates?


Have worked it out, HubSpot stores dates in Unix format.
Zapier has a converter tool built in.


Hi Megan, you're exactly right. We use unix timestamps in milliseconds.
