About the class

This class implements date conversion for the fictitous sci-fi world of Poseidon from the tabletop role-playing game Blue Planet published by Biohazard Games.

See the Blue Planet wiki for more about the Colonial calendar.

Usage

This is a sample session of using the PoseidonDateTime class.

New objects are created with the fromcolonyformat or fromisoformat methods.

Pretty formatting of dates is with the colonyformat or isoformat methods.

The attributes p_year, p_day, p_hour, p_minute, and p_second give the components of the Colonial datetime. Similarly, the attributes year. day, hour, minute, and second give the components of the CE datetime.

You can use timedelta objects for changes in time; PoseidonDateTime.p_day_duration is one Poseidon day and PoseidonDateTime.p_year_duration is one Poseidon year.

>>> import poseidon_datetime as pdt
>>> import datetime as dt
>>> p_atlantis = pdt.PoseidonDateTime.fromisoformat('2124-08-07')
>>> p_atlantis.colonyformat()
'076.33 18:51:43'
>>> p_atlantis.colonyformat(include_time=True)
'076.33 18:51:43'
>>> p_atlantis.colonyformat(include_time=False)
'076.33'
>>> p_birthday = pdt.PoseidonDateTime.fromcolonyformat('023.99 28:15:00')
>>> p_birthday
PoseidonDateTime(2199, 1, 30, 23, 14, 22)
>>> p_birthday.isoformat()
'2199-01-30T23:14:22'
>>> p_birthday.p_day
23
>>> p_birthday.day
30
>>> p_after_birthday = p_birthday + dt.timedelta(days=1)
>>> p_after_birthday.isoformat()
'2199-01-31T23:14:22'
>>> p_after_birthday.colonyformat()
'024.99 22:14:17'
>>> p_after_birthday = p_birthday + pdt.PoseidonDateTime.p_day_duration
>>> p_after_birthday.colonyformat()
'024.99 28:15:00'
>>> p_after_birthday.isoformat()
'2199-02-01T05:15:05'
