2，要求%date%规范2010-02-21 ..... %time%规范 8:43:05.59（最前面有空格）
3，不包含隐藏属性文件

@echo off
set/a D=1%date:~8,2%%%100-1,M=1%date:~5,2%%%100-!D,Y=%date:~0,4%-!M,M+=!M*12,"C=!(M-4)|!(M-6)|!(M-9)|!(M-11)","D+=!D*(!(M-2)*(28+!(Y%%4))+C*30+(!!(M-2)&!C)*31)"
set M=0%M%&set D=0%D%
for /r "指定绝对路径" %%a in (*.txt) do if "%%~ta" lss "%Y%-%M:~-2%-%D:~-2% %time:~0,5%" del /f /a "%%a"
