Problem

Build timestamps in logs and on the server UI are inconsistent when Server and Agents have different TZs

Is it reproducible on Bamboo Data Center?

Environment

Bamboo 8

Steps to Reproduce

1. Configure a Bamboo server with a timezone
2. Configure a Bamboo agent with a different timezone from the Server
3. Run a build on the Bamboo Agent
4. Check the build logs for different timezones in the timestamps
5. Check the build dashboard, it will always refer to the Agent TZ

The timezone can be either inherited from the operating system or forced by a Java user.timezone property

Expected Results

Bamboo should follow a single timezone on the UI and in the logs, preferably the one used on the server.

Actual Results

1. On the build logs, different timezones will pop up on the same log file; being part from the server TZ and part from the agent TZ
   Agent is Australia/Sydney, Server is Pacific/Honolulu

2. On the Bamboo build dashboard, the shown timestamp will always refer to the Agent's timezone and may create confusion if showing a future date in case the Server TZ is way behind the server's.
   E.g Both screenshots are for the same build, the Build result summary reports 18/07, whilst the Recently built dashboard reports 19/07

   Server TZ: Pacific/Honolulu	Agent TZ: Australia/Sydney

Workaround

Use the same timezone on both Bamboo Server and Agents
