Is your feature request related to a problem? Please describe.
There is auto-update interval setting but it drifts by very considerable amount every time tgs deploys new update.

Describe the solution you'd like
Instead of "interval" setting there should be a field for exact times at which TGS should start updates and deployments.

Describe alternatives you've considered
AFAIK time drift happens because it starts counting AFTER deployments. It should count at the start of updates if cron-like setting turns out to be too hard to implement.

Additional context
Auto-update drift very fast. With "every 12 hours" updates it gets additional 1-5 minutes every day and after half a year its already updates at 6 am and pm instead of 12 am and pm
