This is normal and is expected behavior. Transactions are imported and displayed in CoinLedger in UTC time, which you can see in both the Transactions and Tax Reports pages of the app. However, once you generate and download your tax reports, the timestamps of your transactions will be converted back into the timezone that you selected under Tax Settings in your account.

So, do not be alarmed if the timestamps on your transactions vary slightly when viewing them on CoinLedger. They will display properly once you download your reports!
