For Chargebee data, dates and times come in as unix epoch dates and times. Unix epoch time is a system for describing instants in time. It is shown in the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970. If a metric returns points in time in unix time, it will likely show up in milliseconds. You can use SQLite to change it into a readable date and time.
Grow helps you transform these dates and times using SQLite. To do that, read our help article here.
