[JS] the replace statement in parseDate is too greedy

Created by: tray2100

Description

Currently in the parseDate() function it uses replace('/T/', ' ') to convert date strings into something that the Date class can use for construction. This works well for ISO_8601 date strings but it also has the side effect of ruining date strings that have GMT in it.

Current:

new Date(str.replace(/T/i, ' ')) => Wed Apr 15 2020 00:00:00 GM -0700 (Pacific Daylight Time)

Fix:

new Date(str.replace(/(\d)(T)(\d)/i, '$1 $3')) => Wed Apr 15 2020 00:00:00 GMT-0700 (Pacific Daylight Time)

This allows GMT based date strings to work without issue.
