$$TIME$$
$$TIME$$ retrieves the current operating system time. Use $$TIME$$ to designate a default value or range for a text item using the Initial Value or Lowest/Highest Allowed Value properties. The text item must be of the CHAR or TIME data type.
You also can use $$TIME$$ as a default value for form parameters. In this case, the parameter's value is computed once, at form startup.
The display of system variables is governed by the format mask, either a default data type format mask or one you specify. For example, if you want the default HH:MM:SS format, you must specify a TIME data type. (Note that the default format mask depends on the value of NLS_LANG.)
Assume that you want the value of a TIME text item, called ORDERTIME, to default to the current operating system time. When you define the ORDERTIME item, specify $$TIME$$ in the Initial Value property.
