Date and Time Data in Customer.io

Overview

Throughout Customer.io, we try to give you as much insight as we can into what happens and when. We know that timing of messages is critical, so we want to make sure you know exactly when your messages are sent or drafted, for example, or when a particular user was created.

We use your computer’s current time zone for all times, with two exceptions:

  • In exports, we use Coordinated Universal Time (UTC) timestamps.
  • Our dashboard metrics, which are in Eastern Standard Time (EST).

Details

Where we can, we show the full time, date, and your time zone, like this:

When we show you a shorter date (because we know that it’s overkill sometimes), you can hover over it to get more information, like this:

Note: Daylight Savings Time

If you notice that some times are displayed in EDT, PDT, or MDT (for example) but others are shown as happening in EST, PST, or MST respectively, don’t worry! This just means that one event happened while daylight savings time was being observed, and the other did not. It allows us to be just that little bit more accurate.
