Please include your system information as requested at https://github.com/ValveSoftware/steam-for-linux#reporting-issues.
When this happens, have you asked what their system time is?
Likely an all-platfoms issue and not Linux.
19:56 - Benguin: I'm going to restart steam, and then once it says I'm online can you tell me what time your computer's clock has?
19:56 - Clark: Okay
[restarted steam here]
19:57 - Clark: 19:45
19:45 - Benguin: okay thanks
19:45 - Clark: Results?
Everything before "[restarted steam here]" is the greyed-out text that shows messages from last session, apparently that too has the wrong time..

Recent Failure Reports:
This is a known problem that the full Steam team is aware of. Closing this issue as this isn't Linux-related.
Nothing extracted yet.
Every time I restart steam, the first time each person messages me, their timestamp is a couple of minutes early, then all proceeding messages from that person are right. Examples:
The first guy is in a different timezone to me, the second is not.
