A system of telling time where there are 100 seconds in a minute, 100 minutes in an hour, 10 hours in a day, which makes a 100 000 second day. This is different than the current Imperial system of telling time where there are 86 400 seconds in a day. There are currently no countries that use metric time, but that is likely to change.
person 1:Hey what time is it?
person 2:Oh, in metric time it's 5:94
person 1:wtf?!

A system of time with the base measurement of a metric second which is equal to 1/100,000 of a day. There are 100 seconds to a minute, 100 minutes to an hour, and ten hours to a day. So 1 metric hour is equivalent to 2 hrs. 24 min. regular time. So when it is 5.00 metric time it is noon regular time. Midnight on Metric Time starts at 0.00 hrs and runs up to 9.99 hrs. To convert from metric time to regular time take for example 5.85 metric time and multiply by 2.4 which equals the hour with a decimal. Take the decimal and multiply it by 60 to get the minutes in regular time. If you want PM just subtract 12. So 5.85 Metric Time = 14:04 or 2:04 PM.
Ever since Metric Time was established, no one ever gets confused with AM nor PM.

John was meeting his girlfriend for lunch at 5.22 Metric Time.

The incident took place at 2.68.

Used jokingly to refer to confusions that usually arise over multiple systems of measurement.
Bob: It won't take longer than half an hour.
Bill: Is that in metric time?
