After a long week, Friday evening finally felt like drinks o'clock for everyone at the office.

When the messenger arrived, I asked, 'what o'clock is it,' and he checked his pocket watch with a smile.

By the time he reached the meeting, his five o'clock shadow made him look tired.

At my grandparents' local pub on Saturday nights, a noisy six o'clock swill would erupt as tradespeople hurried in to grab pints before the 6pm closing.

By the time we left the office, his five o'clock shadows gave him a rugged look.

When trouble starts, you need a captain who can know what's o'clock and steer everyone to safety.

He ran his fingers over his 5 o'clock shadow and wondered if he should shave before the interview.

I was late to the meeting because of the 5 o'clock traffic.

By the time the meeting ended, several of the men had faint 5 o'clock shadows, which gave them a rugged, tired look.

After a week on the job, he began to know what o'clock it is with the office politics and who to trust.
