Update: I noticed that the syntax for vacationStart and vacationEnd do not permit integer comparisons. So I changed them from 1.3.6.1.4.1.1466.115.121.1.40 to 1.3.6.1.4.1.1466.115.121.1.15. This change allows you to make a gnarwl search string that uses the current time to check if a vacation is active.
