Timeline inaccurate when multiple timezones are involved

The timeline (both the detailed and the regular timelines) in Clarity show incorrect times when the servers are in a different timezone from the user looking at the timeline.

For example, this photo was taken at 3:49pm PST, from a computer in the PST timezone. 

As you can see, it currently shows the local time (red line) as 3:49pm, but it also shows several past events as happening several hours in the future. It seems it's displaying the timestamps from the local timezone of the server, without adjusting to the timezone of the web client.
