davisford / rfc3339.swift
Created May 2, 2019 — forked from kristopherjohnson/rfc3339.swift
Parsing or formatting an RFC 3339 timestamp using NSDateFormatter
View rfc3339.swift
import Foundation
/// Parse RFC 3339 date string to NSDate
/// :param: rfc3339DateTimeString string with format "yyyy-MM-ddTHH:mm:ssZ"
/// :returns: NSDate, or nil if string cannot be parsed
public func dateForRFC3339DateTimeString(rfc3339DateTimeString: String) -> NSDate? {
let formatter = getThreadLocalRFC3339DateFormatter()
return formatter.dateFromString(rfc3339DateTimeString)

FYI: I install ginkgo into $HOME/gocode. My .bash_profile does this:

export GOPATH=$HOME/gocode
export PATH=$PATH:$GOPATH/bin

And I do a custom GOPATH per project. I don't like global GOPATH for all projects. So on projectx, I have to cd projectx && export GOPATH=$(pwd):$GOPATH for example. It is a minor inconvenience, but I think it is cleaner.

This means, I want to install binaries like ginkgo into my global GOPATH and not necessarily my project path. Hope that makes sense.
