====== Function GET-INTERNAL-REAL-TIME ====== ====Syntax==== * **get-internal-real-time** → //internal-time// ====Arguments and Values==== * //internal-time// - a non-negative //[[CL:Glossary:integer]]//. ====Description==== **get-internal-real-time** returns as an //[[CL:Glossary:integer]]// the current time in //[[CL:Glossary:internal time unit|internal time units]]//, relative to an arbitrary time base. The difference between the values of two calls to this function is the amount of elapsed real time (i.e. clock time) between the two calls. ====Examples==== None. ====Side Effects==== None. ====Affected By==== Time of day (i.e. the passage of time). The time base affects the result magnitude. ====Exceptional Situations==== None. ====See Also==== **[[CL:Constant Variables:internal-time-units-per-second|Constant Variable INTERNAL-TIME-UNITS-PER-SECOND]]** ====Notes==== None.
