CLOCK

I am the Watchman and Gatekeeper
I mark the passage of all things
I measure life from birth to reaper
Be you Beggarman or King

Implacable guardian of time I am
Unmoved by pain or pleasure
Sweeping on in perfect iamb
I march with infinite tenure

Silent seconds flash in neon LED
Or mechanical wheel and cog
Time passes by relentlessly
From pro to epilogue

First week back at work - thank crunchie it's Friday :P
