Library (julian), lack of usage information

[snippsat]

Is this not okay?

>>> import julian
>>> import pendulum
>>> 
>>> dt = '2018-09-09 12:12:12.005876'
>>> dt = pendulum.parse(dt)
>>> dt
DateTime(2018, 9, 9, 12, 12, 12, 5876, tzinfo=Timezone('UTC'))
>>> julian.to_jd(dt, fmt='jd')
2458371.0084722904

Same or this is or more correct than Calendar date to Julian date which can take 1 decimal place in seconds.
