Probably a stale issue but anyways:
So schedule.Time
is that user entered initial start date and the cron expression is something like 0 0 */2 * *
In that case when you use GetNextOccurrence()
you will have to supply the last occurrence as input parameter to get the next occurrence. Th first time, ie. when the user sets this up you use the schedule.Time
as last occurrence and the next one is calculated. You could then store that occurrence in schedule.Time, unles you want to keep that value, in that case you will have to store it in another variable/field.
Your workaround also solves this but, as you stated, in a sub-optimal way.
I don't think this is a bug, it's just the way cron works, you supply it a starting point date and a cron expression and it calculates the next occurrence according to the cron expression.

It's a few years later, so now it's definitely stale 😅 but...
If I understand this correctly, you want a method that acts as a shortcut for expression.GetNextOccurrence(DateTime.UtcNow, TimeZoneInfo.Local);
?
Having a dedicated method for this is a bit overkill IMO. If you want the current date, just supply the current date.
