Schedule newsletters with "timezone detection" later

When scheduling a Newsletter and selecting the "timezone detection" option, you previously had to ensure you scheduled the Newsletter at least 24 hours prior to the selected time in the first timezone (GMT+13).

You can now schedule newsletters with "timezone detection" right up until the selected time in the first timezone.

For example, if you are scheduling a newsletter for 9am, 1 August 2019 you can now schedule this newsletter up until 9am GMT+13, 1 August 2019.
