  1. @echo off

  2. echo starttime,%time%

  3. echo starttime,%time%>timeresult.txt

  4. for /r %%i in (*.txt) do (

  5. echo %%~nxi

  6. 

  7. call set t1=%%time%%

  8. 

  9. echo waiting 3 second ...

  10. ping -n 3 127.1>nul

  11. 

  12. call set t2=%%time%%

  13. 

  14. call echo %%t1%%,%%t2%%

  15. call echo %%~nxi,%%t1%%,%%t2%%>>timeresult.txt

  16. )

  17. echo endtime,%time%>>timeresult.txt

  18. echo endtime,%time%

  19. echo complete

set t1, set t2 前不加call也试过了。
谢谢指点！
