[Nice to have] having transformers to get date information from Datetime #6232
Description
ModelBuilder just add support for Datetime type, in order to make the most use of this type, it would be helpful if ML.Net has API to extract specific date information from datetime column
Describe the solution you'd like
class Input
{
public Datetime date {get; set;]
}
var pipeline = mlContext.Transformer.GetYearOutOfDate("year", "date")
.Append(mlContext.Transformer.GetDayOutOfDate("day", "date")
.Append(mlContext.Transformer.GetWeekdayOutOfDate("weekday", "date")
.Append(mlContext.Transformer.GetMonthOutOfDate("month", "date");
class Output
{
public Datetme date {get; set;}
public int Year {get; set;}
public int day {get; set;}
public string Month {get; set;} // Feb, Jan...
public string Weekday {get; set;} // Mon, Tue,..
}What's more
ignore this issue if ML.Net already support that.

@LittleLittleCloud Sorry for the late reply. Check out the FeaturizeTimeDate and ReplaceMissingTimeSeriesValues transforms. They're not in the docs but are part of ML.NET.
Currently tracking adding them to docs in #6333 and #6334
Closing this issue for now.

Reactivating since we're removing Microsoft.ML.Featurizers in #6355. Per offline discussion we think that we could bring back some of these as a managed implementation.
