Global time

Global time is a timescale based on the rotation of the Earth. It is a modern continuation of Greenwich Mean Time (GMT), the mean solar time on the meridian of Greenwich, England which is the conventional 0-meridian for geographic longitude. Time zones are still in operation throughout the world, with each Economic Combine adopting its own standard or local time. By convention, these are computed as an offset from global time. However, the pervasive nature of the VR Net and its associated 24-hour culture means that commerce and broadcasting are instantaneous across the globe. Times in these fields are normally expressed in global time.

Usage
Global 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 "global" or "global time" are normally added after to specify that another time standard is not meant.

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

"At 0920 hours global time this morning, former Reality Secretary Perry Epp was the victim of a kidnapping attempt near his home outside Chicago."

"At 0437 hours global time this morning, an earthquake measuring 6.7 on the Richter scale rumbled through southern California."

"Space shuttle Sea Gull has left Moonbase Wilson with its neutron bomb payload. The World Congress has asked people everywhere to observe a minute of silence at 1200 hours global time tomorrow in support of Colonel Bonestell and his clone soldiers."
