RapidMiner's Nominal to Date operator provides a very powerful parser to deal with various date time formats and automatic standarization to common timezones

This document provides additonal example to work with

 

Wed Mar 25 2015 09:56:24 UTC -0500

Wed Mar 25 2015 09:56:24 UTC +0000

can be parsed using

EEE MMM dd yyyy HH:mm:ss zzz X

 

 

Wed Mar 25 2015 09:56:24 EST

Wed Mar 25 2015 09:56:24 GMT

can be parsed using

EEE MMM dd yyyy HH:mm:ss zzzz

 

2001.07.04 AD at 12:08:56 PDT

can be parsed using

yyyy.MM.dd G 'at' HH:mm:ss z

 

010704120856-0700

can be parsed using

yyMMddHHmmssZ

 

Date and time formats are specified by date and time pattern strings. Within date and time pattern strings, unquoted letters from 'A' to 'Z' and from 'a' to 'z' are interpreted as pattern letters representing the components of a date or time string. Text can be quoted using single quotes (') to avoid interpretation. "''" represents a single quote. All other characters are not interpreted; they're simply copied into the output string during formatting or matched against the input string during parsing.

The following pattern letters are defined (all other characters from 'A' to 'Z' and from 'a' to 'z' are reserved):
