Go filename friendly RFC3339 inspired timestamps

timestamp.go

// GetTimeStamp returns a timestamp in a file name friendly, version of the RFC3339
// format.  The string produced by RFC3339 includes a couple colons ':' that are not
// friendly to most filenames (unix and dos a like).  The colons need to be escaped
// if used in a filename, since they are useless, we'll rip em.
func TimeStamp() string {
	ts := time.Now().UTC().Format(time.RFC3339)
	return strings.Replace(ts, ":", "", -1) // get rid of offensive colons
}

Fixed typo

func TimeStamp() string {
	ts := time.Now().UTC().Format(time.RFC3339)
	return strings.Replace(strings.Replace(ts, ":", "", -1), "-", "", -1)
}

Result
20091110T230000Z

This way might be better for linux files.

Why not directly time.Now().UTC().Format("20060102T150405Z")
