Ok, I found out why (kind of). When I set the outputs for the Start and End Date, Start Date was set to the type “Date” and End Date was set to “Text”. When I set them both to text it worked. It seems that maybe selecting Date means that Make was adding another hour (for daylight savings) when it had already had that hour added previously. Hope this helps someone.

I ran into a similar issue recently, I figured it’s because the timezone setting in make (in my case London GMT+00:00) doesn’t accommodate daylight saving time (British Summer Time, GMT+01:00).
In case it helps anyone; I fixed it in scenario by specifying the timezone whenever parsing a date as text:
{{formatDate(now; “DD.MM.YYY HH:mm”; “Europe/London”)}}
