Hum, it's showing Feb 22 here. I will say that we don't have access to the exact time played on Steam games anymore though, we only get back the month and day. This might impact the accuracy to some degree since it's missing hours from the timestamp.
Specifically, the only last played dates we have access to are the ones listed on the main Steam profile page here under Recent Activity:
https://steamcommunity.com/id/metalmight7/
So you can check if it differs from that, and let me know if so. The timestamps we had access before were accurate down to the second but Valve removed...
