I remember seeing some shots last night (can't remember where, sorry) and the time (and maybe the date as well) was definitely intact on the Mini Guide.
I've tried restarting my own box, but it hasn't updated to the new EPG or branding, we're still stuck on NTL's hideous blue branding. Could it be because the hardware is too old, or is it because there's a different procedure for getting updates these days?
I did try Virgin Media's website. Not a single thing about "should I reboot my box?" or "should I call Virgin Media if my box malfunctions?" It was all about the UI.
If you turn to 999 (channel 999, not the Emergency Services number), you will find JK and Joel who will show you screenshots and give you some trouble-shooting stuff.
