I can do a few tricks to get this:

function                                             old     new   delta
exec_builtin                                           -    1466   +1466
do_mktime                                              -     116    +116
tokenlist                                            441     448      +7
tokeninfo                                            396     400      +4
evaluate                                            5395    3755   -1640
------------------------------------------------------------------------------
(add/remove: 2/0 grow/shrink: 2/1 up/down: 1593/-1640)        Total: -47 bytes


Applied, thanks!
