The buttons in the Date group select the format in which dates are displayed in printed documents. A sample of the format is provided. In the Time group you have the option to enable the display of seconds in documents and in Prescription (Rx) window controls. Display of seconds is disabled by default. (Note: seconds will not be displayed in Rx window controls until you restart the program.) In general, the various date and time controls found throughout the program will automatically comply with your MacOS date and time preference settings.

Time zone group
The Time zone group enables the Plaque Simulator (PS) application to operate as if it were located in a time zone other than the computer's local time zone. This feature is disabled by default and PS uses your computer's local time zone and calendar to calculate plaque removal time and/or implant duration in order to calculate the required source strengths at the time of plaque insertion. The primary reason for setting an application specific time zone is to plan a treatment that will take place in a time zone that observes daylight saving time differently than the local time zone of the planning computer for those infrequent instances when a daylight saving clock change occurs during the implant period and the plaque removal time is predetermined.
For example, in the USA, the state of Arizona does not observe daylight saving time. Lets assume you are planning a treatment that will take place in Phoenix Arizona using a computer located in Los Angeles California. The plaque will be inserted (in Phoenix) on March 10 at 8AM and removed March 17th at 8AM. A clock change for daylight saving time occurs on March 14th and is observed in Los Angeles (where the planning computer is located) but not in Phoenix which remains on mountain standard time. If this implant were done in Los Angeles, the duration would be 167 hours, whereas in Phoenix the duration will be 168 hours. To calculate source calibration strengths for treatment in Phoenix you could enable app. time zones and temporarily select America/Phoenix as the application time zone.
8AM to 8AM treatment in Los Angeles, California (167 hours)
(observes daylight saving time)
8AM to 8AM treatment in Phoenix, Arizona (168 hours)
(does NOT observe daylight saving time)
