AFAIK, there is no better way.  Here is the (similar) example given in
groff.texinfo:

  .sy perl -e 'printf ".nr H %d\\n.nr M %d\\n.nr S %d\\n",\
              (localtime(time))[2,1,0]' > /tmp/x\n[$$]
  .so /tmp/x\n[$$]
  .sy rm /tmp/x\n[$$]
  \nH:\nM:\nS

To use the sy request we need the -U switch which is not optimal.

Maybe we shall add registers to provide the current time also in
gtroff?
