[日期时间] 请教:批处理for中每个循环的起始时间%time%都一样没有变化

@echo off
echo starttime,%time%
echo starttime,%time%>timeresult.txt
for /r %%i in (*.txt) do (
echo %%~nxi

call set t1=%%time%%

echo waiting 3 second ...
ping -n 3 127.1>nul

call set t2=%%time%%

call echo %%t1%%,%%t2%%
call echo %%~nxi,%%t1%%,%%t2%%>>timeresult.txt
)
echo endtime,%time%>>timeresult.txt
echo endtime,%time%
echo complete

set t1, set t2 前不加call也试过了。
谢谢指点！
