Support of conversion of millisecond Unix time to Refine datetime #609

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
It would be nice to have a function such as FORMAT_UTC_USEC to convert Unix 
time ( which is a number) to a Datatime format, and to extract only 
year/month/day

Can you provide a reference for the definition of this function?

Since we already provide a variety of date formatting functions, I'm guessing 
that what you really need is to be able to convert from a microsecond Unix time 
(ie Unix time multiplied by 1,000,000) to a Refine DateTime data type.  From 
there you would be able to use any of the standard date functions.

Yes, it is very common to get the timestamp in microsecond unix time, a google 
example can be seen at rbig query functions 
https://developers.google.com/bigquery/docs/query-reference#timestampfunctions, 
but there are many other places you use it... 
Axtuwlly, I wanted to use refine as part of automatic pre processing of data I 
am getting, and was wondering on size of input, and do it all in thbwckgrounf 
before loading csv to big query...

what is the solution to converting numeric date in milliseconds to a human 
readable date format in 2.5 version of this product?
