Facebook keeps showing strange active sessions

[EpicRazzy]

Facebook keeps showing strange active sessions even though I've changed my password and I have activated the setting to ask for a verification code, which is obtained by Facebook sending a SMS to my phone with, everytime a new device logs on. What is strange with those sessions is that they show hours on which I am sure I didn't access Facebook! Is this a glitch or someone hacked my account?

What is strange about the active sessions aside from the time discrepancy?

Do you notice anything else like wrong location?
