Datetime Strings

This is a beta node. Please visit https://github.com/nortikin/sverchok/pull/2137

This node processes dates formatted as text, and lets you convert them into an ordinal (a day indication, an integer). It also supports the subordinal (float, what percent into the day, seconds / total_seconds_in_day ).

If you intend to use this node it is important that you absorb the documentation that accompanies the Python datetime module. Especially of interest should be strptime and strftime and the examples that demonstrate how to interact with string representations of dates.

Features:

• Ordinal is an integer representing a day, this is the kind of precision that is useful if you are working on the scale of months, years or decades.

• Subordinal is more precise and gives the ratio (using seconds) of how far into the day it is. This date information needs hours/minutes/seconds to be provided. Useful for timescales of hours, days or weeks..

Not yet implemented are Micro-ordinal, which would take milliseconds into account. Such date information would be useful for plotting sub second timeseries… or multi-second, (but not so handy for multi-minute timeseries, generally)

• N-panel / “Make Reference in Texts”. is a toggle that creates a Document in the bpy.data.texts called [DOC] strptime / strftime, this displays the following reference.

Note: Examples are based (http://strftime.org/ by Will McCutchen) on datetime.datetime(2013, 9, 30, 7, 6, 5) Python Docs: https://docs.python.org/3.6/library/datetime.html#strftime-and-strptime-behavior
