time

Functions and classes for handling time

Classes

date	Define a single date; based on pd.Timestamp
Time	Handle time vectors for both simulations and modules.
TimePar	Base class for time-aware parameters, durations and rates
dur	Any number that acts like a duration
rate	Any number that acts like a rate; can be greater than 1
time_prob	A probability over time (a.k.a.
beta	A container for beta (i.e. the disease transmission rate).
rate_prob	An instantaneous rate converted to a probability; must be >=0.

Functions

time_ratio	Calculate the relationship between two sets of time factors
date_add	Add two dates (or integers) together
date_diff	Find the difference between two dates (or integers)
days	Shortcut to ss.dur(value, units='day')
years	Shortcut to ss.dur(value, units='year')
perday	Shortcut to ss.rate(value, units='day')
peryear	Shortcut to ss.rate(value, units='year')
