所以我注意到 %time% 变量在批处理文件的日志中不准确，如下所示。输出包含在代码下方...它在进入 for 循环时获取当前时间，但不会在运行时更新它。这些是大型 zip 文件，有时需要几分钟才能解压缩每个文件。有人知道这里发生了什么吗？

代码：

@echo off
setlocal EnableDelayedExpansion

for /f "tokens=1-26 delims=/:. " %%a in ('echo %date% %time%') do set today=%%d%%b%%c
echo %date% %time% process start >> h:\logfiles\unzip\%today%.log

:BANK1
set bank=BANK1
call:process BANK1LOCKBOX.lbx.6*.zip
call:process BANK1LOCKBOX.lbx.3*.zip

:BANK2
set bank=BANK2
call:process BANK2LOCKBOX.A*.zip PASSWORD1
call:process BANK2LOCKBOX.R*.zip PASSWORD2

echo %date% %time% process complete >> h:\logfiles\unzip\%today%.log
goto:eof

:process
set thisfile=%1
set pword=-y
if not [%2] equ [] set pword=-p%2 -y
if exist f:\banks\%bank%\zipped\%thisfile% (
    echo    %time% %thisfile% begin >> h:\logfiles\unzip\%today%.log
    for /f "tokens=1-2 delims=;" %%a in ('dir /b f:\banks\%bank%\zipped\%thisfile%') do (
        echo        %time% %%a start >> h:\logfiles\unzip\%today%.log
        7z x f:\banks\%bank%\zipped\%%a -of:\banks\%bank%\* %pword%
        if %errorlevel%==0 (
            move /y f:\banks\%bank%\zipped\%%a f:\banks\%bank%\processed\
            echo        %time% %%a complete >> h:\logfiles\unzip\%today%.log
        )
    )
    if exist f:\banks\%bank%\zipped\%thisfile% (
        move /y f:\banks\%bank%\zipped\%thisfile% f:\banks\%bank%\unprocessed\
        echo        %time% %thisfile% failed >> h:\logfiles\unzip\%today%.log
    )
    echo    %time% %thisfile% end >> h:\logfiles\unzip\%today%.log
)

日志如下所示：

%time% 像任何其他 %var% 一样在解析时进行评估。然后将该值替换为执行，因此它不会改变。

如果您想要当前时间，则需要setlocl enabledelayedexpansion使用 AND!time!代替%time%
