This behavior is by-design. The CrontabSchedule method that produces 
occurrences is 
called GetNextOccurrences. The *next* means not including the start time if the 
start 
time is on the boundary of the schedule. So, for example, if it is midnight and 
you 
have the expression * * * * * (meaning every minute) then the next occurrence 
of the 
schedule will be at one minute past midnight and not midnight itself. In your 
example, there are no matches because the start time of 1:10 AM lies on the 
schedule 
and there is no next occurrence until 1:15 AM. If you want to absolutely make 
sure 
that the first boundary case is included, then you should minus one minute or 
less 
from the starting time.

This issue is being closed as WontFix because GetNextOccurrence works as 
advertised. 
The documentation of the methods, however, has been expanded to explain the 
behavior 
more precisely with respect to certain input cases.
