Hello,

  A while ago I tried to add process timing reports to my ZSH and found that
  REPORTTIME feature only can print timings to terminal but I have a great
  prompt with much information embedded and still having some space to add this
  info.

  My suggestion is to add possibility of exporting timings to envvars instead
  of printing them to terminal.

  My straightforward implementation is attached: while REPORTTIME is switched
  on if REPORTTIME_TO_VAR is defined then four variables are set up:
  REPORTTIME_USER, REPORTTIME_SYSTEM, REPORTTIME_TOTAL and REPORTTIME_CPU. The
  numbers are just summed up for all procs over the job. Don't know if it's a
  good idea to extract timing computation to a new function, so I just copied
  it from `printtime'.

  Will this feature be useful for someone else?

Best Regards,
Slava Barinov.
