Time exceptions are "global", which means that once a time exception is defined it can be selected by one or more jobs. A time exception is a complement to the Time trigger settings.
If defined, a time exception collection can be selected for a job. The activated collections include time definitions when the job will NOT run, i.e. blocking time(s) and interval(s) set in the other Time settings sub tabs.
Time exceptions is a way to skip execution of a job at a certain time or interval. A time exception collection is a package of one or more time exceptions. For example, a time exception collection may be "American Holidays" and one time exception could be the 4th of July. If you, for example, have a job that runs every day and you want to skip running that job on "American holidays", you check the time exception collection "American holidays" for this job.
Collections with time exceptions are managed either from the main menu Manage -> Manage time exceptions dialog or from the Add job/Edit job menu under the Time exceptions tab. When adding a collection, you can specify a name and a appropriate description. When a collection has been created, time exceptions can be added. Each collection is expandable, and when expanded, the underlying time exceptions are displayed. Setting of time exceptions work the same way as time settings for a job. Collections and exceptions are managed (add, edit and delete) by mouse right-click in the collection/time exception list. During changes in the time settings, the Next exception time will be calculated at the status bar.
Also, time exceptions and collections may be managed directly from a job in the Time settings -> Time exceptions tab.
Note: Remember that a change of a collection affects all jobs that use that specific collection.
Import and Export selected time exception collections at the VisualCron website, all kinds of collections will be publicly available with, for example, holidays for different countries. An important feature is the import function. The import function can import collections that you or another person has created. If a collection already exists you'll be asked if you want to replace or skip the import of that collection. You the import functionality from the Time exceptions main menu Collections -> Import.
The time exception settings are stored by VisualCron in the timeexceptions.xml file, by default stored in the "C:\Program files\VisualCron 4\settings" folder.
