In addition to the value of a DataHub point, you might need to know its timestamp or quality at the moment of an event. This information can be accessed through two special Gamma scripts: Time.g and Quality.g. You can require these scripts by adding a require function at the beginning of your script, like this:

require ("Application");
...
require ("Time");
require ("Quality");
...

The Time.g script offers a number of time-related functions, while the Quality.g file has a single function that converts a numerical quality code into a human-readable text string. These scripts are both located in the require folder of your DataHub installation.
