How difficult is it to understand the concept of the 24 hour clock, used as far as I know in most countries?
This caught my eye just now, watching the American TV series Homeland
The digital clock in the wall, this scene from the CIA headquarters in Virginia, US:
The Langley time might or might not be correct, 19:20 if the screenwriters intended this scene to happen at 7:20 PM. But then, see the Zulu time (UTC / GMT time), and the Islamabad time (Pakistan, shortened in the wall as IBD). For the Homeland production team's information, the time in 24 hour clock can never be 25 something or 29 something; it can only be something between 00:00 and 23:59. Midnight is 00:00, noon 12:00.
Not to mention the other time related error in this scene: Zulu time means UTC (previously called GMT). UTC time is 5 hours ahead of Langley time EST or 4 hours ahead Langley time EDT. Never six hours ahead.
