[GAP Forum] Save “time” in a variable in GAP

Yes, time is just like a variable (this is different to the time command in unix and other systems):

   a:=ConstructAllGroups(10);;savedtime:=time;

Within a program I would rather refer to the value of Runtime(), that is:

start:=Runtime();
a:=ConstructAllPiffles(-33);
total:=Runtime()-start;
