I'm walking down the hallway of the CS building. I wonder what time it is. I check my wrist, but I'm not wearing a watch today.
I reach into my pocket and withdraw an item. It isn't displaying the time, so I flip it over. Maybe that side will tell me the time.
No luck. I scrutinize the first side again, but still don't know what time it is. Why won't this thing tell me the time?! What is wrong here?
Then it hits me.
I'm not staring at any sort of time-telling device. Not my phone. Not my iPod. This thing in my hand is a plastic ID card. Ah. Right.
I do reach one chronographic conclusion: it has been a long week.
