Time error

I am in the UK, which is now in summer (daylights saving) time. The time shown on Solarwinds differs from the windows time. See the image below. When I first select a map the time on the map matches that in the windows taskbar, but as soon as the map is fully displayed the time switches to about one minute behind UTC. To add to the confusion the PC is set to UTC, see below.

Any ideas what's going on here?
