timezone to UTC

[nikhi1993]

hi, after upgrading to akhq 0.25.1, I'm seeing timestamp displayed on ui varies w.r.t region. I have tried to add env variable to akhq values file as below, but its not taking any effect. :

`extraEnv: |

• name: JAVA_OPTS
  value: "-Duser.timezone=UTC"`

any suggestions would be really appreciated.
Thank you!
