When using the TZ expression in Cron I was thinking that when you navigate away and it gives you the message when it would have last run(ex: Would last have run at Thursday, September 29, 2016 11:55:02 AM EDT; would next run at Thursday, September 29, 2016 11:55:02 AM EDT.), I think that it should reflect that Timezone that is listed in the expression rather than the current Jenkins one right?

In the screenshot I have a TZ of Los Angeles but my Jenkins is configured to be EDT I would think it should reflect PDT instead since I changed the timezone.
