clockblock 

When you're looking forward to leaving work early or on time, but are kept late either by a new assignment from your boss or a chatty coworker.

I was all set to rush out of work at 5:00, but then I got totally clockblocked by my boss and wound up staying till almost 7.

Clockblock 

When your online friends have a different timezone than you, so you can't chat with them.

I woke up in the morning to talk to my friend when I realized he was across the world from me, still sleeping. Dammit , I was clockblocked!
