GetOcccurances from and to inclusive does not work

Hi!

Could be me misunderstanding something, but im getting different results with the following call:

DateTime startTime = {'5/20/2022 12:00:00 AM' }; //obv as a DateTime object
DateTime endTime= {'5/31/2022 12:00:00 AM' }; // obv as a DateTime object
string expression = '0 0 9 * * 1,2,3,4,5';
var cron = cronExpression.Parse(expression , CronFormat.IncludeSeconds);
cronExpression.GetOccurances(startTime, endTime, true, true).
this returns, as expected the following:
5/20/2022 9:00
5/23/2022 9:00
5/24/2022 9:00
5/25/2022 9:00
5/26/2022 9:00
5/27/2022 9:00
5/30/2022 9:00

however, changing the expression to the following
string expression = '0 0 0 * * 1,2,3,4,5';

removes 5/20 from the list, despite it being the exact same call?

I could theoretically move the input times back by a second, but that's a hacky fix id rather not do.

Again, not sure if this is expected behavior, or if I'm just being dumb. Let me know if you can help. Thanks!
