Galactic Mean Time

Galactic Mean Time or Galactic Standard Time was proposed by Guild Navigation in order to standardize time across colonized space. The time measurement system and indeed the term itself are both borrowed from old Earth: 60 seconds to a minute, 60 minutes to an hour, 24 hours to a day, and so on. Nearly all worlds connected by Guild gates use Galactic Mean Time; standardization is next to godliness, after all.
Interestingly, there is no planet on file aside from Earth whose day matches perfectly with a galactic standard day. Some planets with highly irregular day/night cycles will refer to Rotations when formatting work schedules which depend on specific light conditions to be performed.
===The current year?===
A GuildNav standard calendar measures a 'year' as being 8765.81277 GMT hours. This differs from individual planetary revolutions or rotations, but provides a standard of reckoning the universal date. Each GuildNav gate transmits the current date and the hours into it to nearby vessels, and marks that information down as ships pass through.
The current year is 6443 AS - Abeo Sol. This era began on the vanishing of the Solar system from its prior position in galactic charts, 4617.343 hours into the year 6016CE. Some colonies still follow other calendar systems, though these are quite rare.
