Questions about face book messenger timestamp and face book mobile app timestamp?

[jellybean*nc]

I have an iphone 4, my friend has an android phone a razr. Up until about 4 or 5 days ago the time stamps in both the messenger app for the phone and the face book mobile app were the same for showing when last active, now if I go into face book mobile on my phone, beside his name in the chat column there will be one time beside the mobile phone icon but if I open face book messenger app, tap his name the time that shows is quite different than what is shown in the chat column, I thought that they were integrated? why would I be getting two completely different times, by several hours? In other words Facebook Messenger, would appear like this: John Doe 8hrs with mobile phone icon, I actually tap his name to send or read a message and underneath his name when the message screen opens it will say last active 2hrs. Go into the actual face book mobile app and the same thing happens 8 hrs with the mobile phone icon beside name in the chat column but you tap the name as if you are going to send a message and a completely different time appears under the name. He did say that he upgraded his app so I wonder if it's a glitch in the new version? Curious as to why this is happening.
