In the Generator Block, you now have the option to select "AtStartTime" in the UTC Time zone. You can also set the UTC Date as well. In the below screen shot, you will see I have made 2 samples of the Generator Block set for a specific Time Trigger. Then there is also a "repeating message" set for every second....or 1000 milliseconds in this case.
