Chart tooltip shows timestamp with milliseconds even if 'full_date' options doesn`t have it

grafana v7.5.2
The option is configured via environment variable:

Table panel contains right formatted datetime values, but the chart tooltip shows datetime values with 3-digit milliseconds at the end. How can I avoid them?

Hi @sbaryshnikov

Three quick questions:

  • what datasource are you using
  • if you go to inspect => data and then view/export the data, what do the raw timestamps look like
  • Have you tried upgrading to Grafana 8? Curious to know if this issues persists in the newest releaseā€¦

Thanks for your help, and welcome to the forum!
