Function proposal: parseDateTime #133

Closed leongor closed 6 years ago

leongor commented 6 years ago

Recently we've developed parseDateTime function for Streams Designer. Here 2 main reasons behind it:

  1. fromIso8601ToTimestamp function from com.ibm.streamsx.datetime toolkit is very strict, while customers frequently use timestamps without time zones or nanseconds.
  2. A single tuple can easily have multiple timestamps to parse, so performance is crucial. parseDateTime is built over Boost.Spirit, one of the blazing fast C++ parsers.

I would propose to merge this functionality to com.ibm.streamsx.datetime to reduce the number of toolkits that handle similar tasks. In the long term I think this function as well as the functions from streamsx.datetime should go into the standard SPL toolkit in spl.time namespace.

Shouldn't this be an issue in streamsx.datetime?

leongor commented 6 years ago

@ddebrunner Yes, right. I'll move it there.

Moved to streamsx.datetime
