What property type and format should a format like hs_analytics_last_timestamp be in? This is a field created by Hubspot. According to Hubspot, this is a single line text field, stored in milliseconds. If I try to recreate this, it does nothing but show the milliseconds. A datepicker field will only be the date, but what if I want the time? It looks like we could use the single line text, and store it as YYYY-MM-DD HH:MM to help with ordering, but there has to be a better way.
The goal would be to have the Last Seen data formatting within the web app, with a custom property we create.
