Day/hour/etc encoding for the ORDER BY column

[tomhuds]

Often additional features proposed to users include day_of_week, weekend, hour_of_day etc.

In the encoding of the time variable, could we add these columns as additional inputs?

Nice timing, I was actually trying this on #937 which wrongly figures as merged but is very much WIP. Last tests indicated worse performance, but this is counterintuitive so I wanted to try and give it another go.

EDIT: It's not a full coverage of the things mentioned in OP, e.g.weekend as such is not a new binary column that gets added, rather just day_of_week and other descriptors according to the DatetimeEncoder logic.

EDIT 2: List of things to try:

• day_of_year
• day_of_week
• hour_of_day
• is_weekend
• quarter_of_year
• month_of_year
• year
• week_of_year

Closing. Should be solved by the sinusoidal datetime encoder. Will decide with #1157 whether to mark it as default.
