我正在尝试编写一个批处理脚本，以安全的方式(即独立于日期格式)获取当前的日期、月份和年份。不幸的是，我发现的所有互联网资源都提出了类似的建议:

   SET CURRENT_DATE=%DATE: =0%
   SET YEAR=%DATE:~-4%
   SET MONTH=%DATE:~3,2%
   SET DAY=%DATE:~5,2%

如果我的日期是 yyyy/mm/dd 或 yyyy-mm-dd 格式，这将起作用，但如果它是 yy-mm-dd 或其他格式，则不会。有没有一种安全的方法来获取年月日？

还有一个问题 - 是否可以知道日期分隔符是什么(第一种情况下为 / ，其他情况下为 - )。

最佳答案

此代码的前四行将为您提供在 XP Pro 及更高版本中可靠的 YY DD MM YYYY HH Min Sec 变量。

@echo off
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"
set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"

set "datestamp=%YYYY%%MM%%DD%" & set "timestamp=%HH%%Min%%Sec%"
set "fullstamp=%YYYY%-%MM%-%DD%_%HH%-%Min%-%Sec%"
echo datestamp: "%datestamp%"
echo timestamp: "%timestamp%"
echo fullstamp: "%fullstamp%"
pause

这是一个 VBS 解决方案:
