[GAP Forum] command to retrieve current date/time

[Sandeep Murthy]

Hi,

It seems an example is given on p. 148 of the GAP Reference
Manual, using the Process function to call the OS date/time
function.  I guess, you could do something like this ...

gap> date := Filename( DirectoriesSystemPrograms(), "date" );
gap> startTime := ""; a := OutputTextString( startTime, true );
gap> Process( DirectoryCurrent(), date, InputTextNone(), a, [] );

.... your computations ...

gap> currTime := ""; b := OutputTextString( currTime, true );
gap> Process( DirectoryCurrent(), date, InputTextNone(), b, [] );
gap> startTime; currTime;

Sincerely, Sandeep.
