opened on Feb 24, 2021

It can be very useful to extract certain "fields" from the timestamp, such as the year, month, day, etc.

See eg https://pandas.pydata.org/docs/user_guide/timeseries.html#time-date-components for the ones available in pandas.

Using pandas as an example, there are the basic components of the datetime:

>>> ts = pd.Timestamp.now()
>>> tsTimestamp('2021-02-24 10:47:54.294504')
>>> ts.year2021
>>> ts.month2
>>> ts.day24
>>> ts.hour10
>>> ts.minute49
>>> ts.second54
>>> ts.microsecond607393
>>> ts.nanosecond0

(only for the sub-second, this is not fully clear how to divide it in microseconds or milliseconds, etc)

But in addition also some more "advanced" like:

>>> ts.dayofyear55
>>> ts.dayofweek2
>>> ts.week8
>>> ts.isocalendar()

              It can be very useful to extract certain "fields" from the timestamp, such as the year, month, day, etc.
              See eg https://pandas.pydata.org/docs/user_guide/timeseries.html#time-date-components for the ones available in pandas.
              Using pandas as an example, there are the basic components of the datetime:
              >>> ts = pd.Timestamp.now()
>>> tsTimestamp('2021-02-24 10:47:54.294504')
>>> ts.year2021
>>> ts.month2
>>> ts.day24
>>> ts.hour10
>>> ts.minute49
>>> ts.second54
>>> ts.microsecond607393
>>> ts.nanosecond0
              (only for the sub-second, this is not fully clear how to divide it in microseconds or milliseconds, etc)
              But in addition also some more "advanced" like:
              >>> ts.dayofyear55
>>> ts.dayofweek2
>>> ts.week8
>>> ts.isocalendar()
