## Timeline of updates

- **resolved** 2019-02-22 01:04 UTC: An issue affecting timestamps for a subset of events was identified on February 14th. The cause of this bug was a software update on our servers last week that caused the timezone offset of projects to not be applied to events at ingestion. This resulted in some events being stored in UTC time in projects. If your project is in UTC then you will be unaffected. Our engineering team deployed a fix in two stages: the first on the afternoon of February 14 and the second on the morning of February 16th. This has caused projects to see an anomaly in event volume around 3PM and 4PM PST on February 14th when the first fix went out causing events moving forward to appear with accurate timestamps. There was no data loss and all the events sent to Mixpanel were tracked in your project.
