E-Prime 2.0 SP1 (22.214.171.1243) introduced an easier way to configure the SNTP clock in E-Prime. When the E-Prime SNTP Realtime Clock is selected in the Experiment Object Properties pages, you can gain access and edit properties of the SNTPClockExtension.ini file from the Graphical User Interface (GUI). Previously, users had to launch a text editor outside of E-Studio to create or edit the SNTPClockExtension.ini file.
E-Prime provides the ability to choose from available clocks via the E-Studio GUI. One of the available clocks is the SNTP Realtime Clock. In order to allow E-Prime to use the SNTP Realtime Clock, additional configuration property settings must be specified in an .ini file; see NEW FEATURE: E-Prime SNTP Realtime Clock  for details.
To expedite the editing process for the SNTPClockExtension.ini file, a new feature exists that allows you to access the contents of this file directly from E-Studio's GUI. This can be found by opening any instance of E-Studio and double-clicking on the Experiment Object. Once the Experiment Object is opened, you can navigate to the Timing tab and set the Clock property to "E-Prime SNTP Realtime Clock".
Beneath the Clock Scale property is the SNTPClockExtension.ini control. Two buttons are available. "Edit My Experiments" searches for and opens the SNTPClockExtension.ini file located in the My Experiments folder. "Edit Program Folder" opens the SNTPClockExtension.ini file located in E-Prime's Program folder (C:\Program Files (x86)\PST\E-Prime [Version #]\Program). If E-Prime does not find a SNTPClockExtension.ini file in the selected location, then E-Prime creates a template version of the SNTPClockExtension.ini file in the selected location (My Experiments or Program folder) and opens the file for editing in Notepad, as shown below:
The template version is an annotated version of the SNTPClockExtension.ini file that explains the purpose of each value and provides a placeholder for each value. Once the proper values have been entered and the SNTPClockExtension.ini file has been saved, E-Prime is able to use the SNTP Realtime Clock.
