The **Standard Galactic Time Unit** or SGTU is the time unit used for standard communication of time across the many planets and polities of the [[Galactic Cooperation Treaty Organisation|Larana/Galactic Cooperation Treaty Organisation]].
|
||||
|
||||
It is defined as followed:
|
||||
|
||||
SGTU quantities are oft expressed either in binary (for the computers), or hexadecimal (for the normal folks)
|
||||
1 SGTU is the length \\(2^{32}\\) periods of the wavelength emited by the [[Ly-α|https://en.wikipedia.org/wiki/Lyman-alpha]] transition of the Hydrogen atom. This amounts to about 1.74µs
|
||||
|
||||
SGTU Timestamps are expressed as a the number of SGTU elapsed since the founding of the GCTO.
|
||||
when written they are typically written in groups of 4 hex digits followed by another delimiter and the number of groups the precison omits, the last group may also contain less than 4 digits in which case the lowest significan digits are assumed to be ommitted. e.g. `123F.12/1` is assumed to be equivalent to `123F.12XX.XXXX` (where X is not specified). the start of the timestamp may also be omitted when redundant, in practice it is rare that more than 2 or 3 groups are ever written, unless the activity requires full precision and/or unambiguity.
|
||||
|
||||
example:
|
||||
|
||||
30 September 2065, 13:12 UTC+2 would be oft renderd as `3D13.65/1` or `18F.3D13.6556.6AD9` for full specificity

Keeping track of time in a meaningful way when your polity controls a dozen worlds and has trade relations with at least 5 dozen more is hard. Thus was invented the [[Standard Galactic Time Unit]]. With that system, interplanetary (and interstellar) activities have a common neutral time system to synchronise things such has [[Faster than Light Communication]], while planet-side affairs typically use a mix of the expressing an absolute unit in the largest SGTU subunit that’ll fit in a local day, to which is added a SGTU duration after the local normalised sunrise.
|
||||
|
||||
For example Earth’s 30 September 2065, 13:12 UTC would be `3D13.65/1` (or `18F.3D13.6556.6AD9` for full specificity) in interstelar communication, but would be refered to as something like `3D13.6/1L+1b1af/1` "on the day that starts on `3D13.6/1` according to the `L`ocal standardised day, at `1b1af/1` past local standardised midnight.
|
||||
|
||||
Note however that, as of 2376, Earth, despite being a signatory of the GTCO still seldom use SGTUs in planetary affairs, oft chosing to use it’s legacy base 60 time system

There are two categories of transportation that are of interest to the galactic
|
||||
traveller: interstellar transport, and planetary transport.
|
||||
|
||||
Planetary transport vary greatly from one world to the next, be it the grand
|
||||
railways of Ȝħarqalin-Wiirèe, getting you most places on the main continent
|
||||
under a day, the relentless aeronautic industry of Telùs-Sol, or the high speed
|
||||
drone taxis which zip in all directions accross and between the Lissiya’s
|
||||
arboreal cities. The best way to know how to get around a planet is to ask the
|
||||
locals
|
||||
|
||||
Interstellar travel on the other hand is — at least within the members Galactic
|
||||
Cooperation Treaty Organisation — much more codified. Space lanes are cleared
|
||||
of most everything by the organisations to allow for supraluminic travel
|
||||
without risking the structural integrity of the ships[¹](#note1). Thus space
|
||||
travel follows the routes of those cleared lanes, as travelling outside the
|
||||
lanes is an activity only reasonable to those who are either thrill-seekers,
|
||||
stupid, owners insanely overkill EM shielding, trying to evade the law, or any
|
||||
combination of the above.
|
||||
|
||||
From this you essentially have five options when arriving at the spaceport.
|
||||
|
||||
The option most common among the majority of travellers is to hitch a ride on
|
||||
one of many a crago vessel (most have a handful of cabins spare in the crew
|
||||
quarters), in exchange for a relatively modest sum or some work on the ship
|
||||
during the transit if you have relevant skills. It’s not fast, it’s not the
|
||||
most comfortable, but it will get you around for a minimal price.
|
||||
|
||||
If you are travelling a common route, a more comfortable — if a bit more
|
||||
expensive — option is to book a slot in one of the regular line ships that
|
||||
ferry passengers around.
|
||||
|
||||
Going up sharply in price, if your origin or destination is hard to reach or if
|
||||
you want the most speed and/or comfort, you can also charter a ship for your
|
||||
trip.
|
||||
|
||||
If however you are on the tightest of budgets and even a hitching on a cargo
|
||||
ship is too expensive, some freight companies offer stasis travel. Basically
|
||||
you get into a stasis box, they turn on the box, handle you in your stasis box
|
||||
like normal cargo and they turn off the box when you arrive, subjectively it’s
|
||||
instant, objectively, it’s as fast as the freight company is, which is
|
||||
typically "not fast", also quite nerve wrecking: if you get lost in shipping,
|
||||
well the energy core in the stasis boxes are typically good for a millenia or
|
||||
two, after which you may wake up to a radically different galaxy. If you don’t
|
||||
wake up in the vaccum of space.
|
||||
|
||||
Lastly, if you are on are travelling between planets of the United Peoples’
|
||||
Federation or some of their closest allies, you’ll have the opportunity to use
|
||||
a jump array. For a frankly insultingly low price, you get put into a perfectly
|
||||
tuned wormhole and appear on the other side instantly for you (you are
|
||||
transported within a stasis field, because directly exposing organics to a
|
||||
wormhole has... undesirable effects[²](#note2)) and a couple of seconds for the
|
||||
rest of the Universe
