# Server Time Zone Changes

Marketing Cloud Engagement servers use the Central Standard Time zone (CST), but don’t observe Daylight Savings Time (DST).

## Further Daylight Savings Time Impact

Systems always remain on Central Standard Time and never change to or from Central Daylight Time in March and November, respectively. Systems are always -0600 from GMT at all times of the year.

## Synchronize Local System Clocks with UTC Time

If necessary, synchronize your local system clocks with the UTC time.

If your local clocks are deployed on Amazon Web Services, use Network Time Protocol (NTP) sources. See [Keeping Time With Amazon Time Sync Service](https://aws.amazon.com/blogs/aws/keeping-time-with-amazon-time-sync-service/).

If your local clocks are deployed outside of Amazon Web Services, use one of the NIST Internet Time Servers. See [NIST Internet Time Service (ITS)](https://www.nist.gov/pml/time-and-frequency-division/time-distribution/internet-time-service-its).

Note Note: For Indianapolis teams in the Central Standard Time zone, servers are one hour behind during winter, but are two hours behind during spring, summer, and fall while observing Eastern Daylight Time (EDT).
