Lunar time

Lunar time is a standardised timescale used on the lunar colonies. It is based on global time, offset by six hours. Just as most commercial, scientific and broadcasting activity on Earth uses one time system, so the lunar colonies all use lunar time. When the colonies were first established, each used the local time in its parent Combine. However, this lead to increasing difficulties in communication so one time zone was introduced for the whole moon.

Usage
Lunar time is written in 24-hour notation with no punctuation between the hours and minutes, thus: hhmm. The time is often followed by the word "hours" to clarify that the speaker is referring to a time of day. A leading zero is added for the hours before 10:00, and this is pronounced as well as in: "oh three oh five hours" for 03:05. The words "lunar" or "lunar time" are normally added after to specify that another time standard is not meant. When lunar time is referred to on Earth it is usual for global time to be specified first, followed by the lunar equivalent.

Example
"Tune to the Edumerge Channel today at 1530 global, 2130 lunar for a special report."
