I'll have to resort to reading the actual source code implementation to have any clue what to do. How to get length of an array and sequence in Nim? So I could believe, leaving the second parameter and using the default timezone does the trick, but is that guaranteed? The Europe/Berlin time zone was running an hour ahead of UTC at that moment then, so an hour ahead of 1 AM is 2 AM same moment, same point on the timeline, different wall-clock time. If you want the first moment of the day on that date, you must specify the context of a time zone. The result is 1 AM on the first day of 1970 as seen in UTC. ZonedDateTime is an immutable object that holds a date-time value to a precision of nanoseconds, a time zone value based on the ISO 8601 calendar system, and a ZoneOffSet to handle ambiguous local date-times. It is a long number also called UNIX timestamp, How do you convert this number to date and time format? So, lets see what other options we have.
