Are the hands importing with the correct timestamp in PokerTracker 4 when compared to your local time? Have you moved timezone recently? On what poker site is this? If you are playing on iPoker they do not specify the timezone in their hand histories so you should set the time in the iPoker lobby to server time and not your local time. Then in PokerTracker 4 go to 'Configure > Sites & Import Options > iPoker' and select the skin you play at, or if it isn't listed one which uses the same server timezone as your skin. If you need further assistance please open a
Support Ticket with all of the answers to the questions I asked above, a screenshot of the issue, your PokerTracker4.log file and hand history sample:
