What time is it?

I think this was lunchtime. Sometimes I work night shifts. Which I quite like, but it really plays havoc with the body clock. I finish work, come home and make breakfast. Or is it dinner? Then I try and figure out when I can sleep. Or should I stay awake until night time? Or is it night time now? Particularly in summer when it's light for most of the 24 hours. And another confusion which I have brought on myself is having this clock in the living room. Doesn't help really.
