"Close enough" time that makes sense when reading it.
Port of date-fns.formatDistance
There are two methods time_between and time_since.
time_between takes two datetime objects and returns the time elapsed.
time_since takes a single datetime object and calculates the difference between that and now.
from datetime import datetime
import humantime
jan_1st = datetime(year=2015, month=1, day=1)
seconds_later = datetime(year=2015, month=1, day=1, second=15)
print(humantime.time_between(jan_1st, seconds_later))
# "less than a minute"
