# Supported time zone formats

These are the values we support when you use the `timezone` attribute in your emails and attributes. Note that we support [automatic geolocation data collection](/journeys/geolocation-data/) as well. If you use automatic geolocation data collection, we’ll set a `cio_timezone` attribute that you can use with our time zone-related features, so you don’t need to set the `timezone` attribute.

*   [Region Format](#region-format) - Supported in our emails and attributes as well as the [Time Zone Match](/journeys/timezone-match/) feature.
*   [Detailed Format](#detailed-format) - Supported in our emails and attributes but **NOT** in our Time Zone Match feature.

### A note on Etc/GMT time zones[](#a-note-on-etcgmt-time-zones)

We support Etc/GMT time zones, but note that the standard is not intuitive. Etc/GMT+2, for instance, means two hours BEHIND GMT, though you might expect it to be ahead because of the “+”. “+” translates to behind GMT and “-” translates to ahead of GMT:

*   Etc/GMT+2 - two hours behind GMT
*   Etc/GMT-2 - two hours ahead of GMT

## Detailed Format[](#detailed-format)

Remember this format is supported in our emails and attributes. It **IS NOT** supported for the [Time Zone Match](/journeys/timezone-match/) feature. For that, use the [Region format](#region-format) above instead.
