Groovy String to Date

I am coding this with Groovy

I am currently trying to convert a string that I have to a date without having to do anything too tedious. 

String theDate = "28/09/2010 16:02:43";
def newdate = new Date().parse("d/M/yyyy H:m:s", theDate)

Output: 

Tue Aug 10 16:02:43 PST 2010

The above code works just fine, however when my string changes to something like:

String testDate = "Tue Aug 10 16:02:43 PST 2010"
def newerdate = new Date().parse("d/M/yyyy H:m:s", testDate)

It tells me that "there is no such value for Tue". I tried to throw an 'E' in the parse for the date but it said the date was not able to be parsed.

Can someone explain how I should go about parsing the second example?

I think the best easy way in this case is to use parseToStringDate which is part of GDK (Groovy JDK enhancements):

Parse a String matching the pattern EEE MMM dd HH:mm:ss zzz yyyy containing US-locale-constants only (e.g. Sat for Saturdays). Such a string is generated by the toString method of Date

Example:

println(Date.parseToStringDate("Tue Aug 10 16:02:43 PST 2010").format('MM-dd-yyyy'))

Below is the way we are going within our developing application.

import java.text.SimpleDateFormat

String newDateAdded = "2018-11-11T09:30:31"
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss")
Date dateAdded = dateFormat.parse(newDateAdded)

println(dateAdded)

The output looks like

Sun Nov 11 09:30:31 GMT 2018

In your example, we could adjust a bit to meet your need. If I were you, I will do:

String datePattern = "d/M/yyyy H:m:s"
String theDate = "28/09/2010 16:02:43"
SimpleDateFormat df = new SimpleDateFormat(datePattern)
println df.parse(theDate)

I hope this would help you much.
