在Windows (Windows XP)批处理脚本中，我需要格式化当前日期和时间，以便以后在文件名等中使用。
这类似于堆栈溢出问题如何在批处理文件中添加日期，但也包含时间。
到目前为止，我有这个:
echo %DATE%
echo %TIME%
set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__%time:~0,2%_%time:~3,2%_%time:~6,2%
echo %datetimef%
这使:
28/07/2009
8:35:31.01
2009_07_28__ 8_36_01
是否有一种方法可以允许%TIME%中的个位数小时，以便我可以得到以下结果?
2009_07_28__08_36_01

在这种情况下，使用简单、标准的编程方法: 与其花费大量精力解析未知实体，不如简单地保存当前配置，将其重置为已知状态，提取信息，然后恢复原始状态。只使用标准的Windows资源。
具体来说，日期和时间格式存储在注册表项下 HKCU\Control Panel\International\ [MS定义]"values": " timeformat "及"sShortDate"。 Reg是包含在所有Windows版本中的控制台注册表编辑器。 修改HKCU密钥不需要提升权限
Prompt $N:$D $T$G
::Save current config to a temporary (unique name) subkey, Exit if copy fails
Set DateTime=
Set ran=%Random%
Reg copy "HKCU\Control Panel\International" "HKCU\Control Panel\International-Temp%ran%" /f
If ErrorLevel 1 GoTO :EOF
::Reset the date format to your desired output format (take effect immediately)
::Resetting the time format is useless as it only affect subsequent console windows
::Reg add "HKCU\Control Panel\International" /v sTimeFormat /d "HH_mm_ss" /f
Reg add "HKCU\Control Panel\International" /v sShortDate /d "yyyy_MM_dd" /f
::Concatenate the time and (reformatted) date strings, replace any embedded blanks with zeros
Set DateTime=%date%__%time:~0,2%_%time:~3,2%_%time:~6,2%
Set DateTime=%DateTime: =0%
::Restore the original config and delete the temp subkey, Exit if restore fails
Reg copy "HKCU\Control Panel\International-Temp%ran%" "HKCU\Control Panel\International" /f
If ErrorLevel 1 GoTO :EOF
Reg delete "HKCU\Control Panel\International-Temp%ran%" /f
简单，直接，应该适用于所有地区。
出于我不理解的原因，重置“sShortDate”值立即生效 一个控制台窗口，但重置非常相似的“sTimeFormat”值不会生效 直到打开一个新的控制台窗口。但是，唯一可以更改的是分隔符- 数字的位置是固定的。同样，“HH”时间标记应该在前导零之前，但它没有。 幸运的是，变通方法很简单。

REM Assumes UK style date format for date environment variable (DD/MM/YYYY).
REM Assumes times before 10:00:00 (10am) displayed padded with a space instead of a zero.
REM If first character of time is a space (less than 1) then set DATETIME to:
REM YYYY-MM-DD-0h-mm-ss
REM Otherwise, set DATETIME to:
REM YYYY-MM-DD-HH-mm-ss
REM Year, month, day format provides better filename sorting (otherwise, days grouped
REM together when sorted alphabetically).
IF "%time:~0,1%" LSS "1" (
SET DATETIME=%date:~6,4%-%date:~3,2%-%date:~0,2%-0%time:~1,1%-%time:~3,2%-%time:~6,2%
) ELSE (
SET DATETIME=%date:~6,4%-%date:~3,2%-%date:~0,2%-%time:~0,2%-%time:~3,2%-%time:~6,2%
)
ECHO %DATETIME%
以下可能不是一个直接的答案，但一个接近的答案?
set hour=%time:~0,2%
if "%hour:~0,1%" == " " set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__0%time:~1,2%_%time:~3,2%_%time:~6,2%
else set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__%time:~0,2%_%time:~3,2%_%time:~6,2%
至少这可能是鼓舞人心的。
set hourstr = %time:~0,2%
if "%time:~0,1%"==" " (set hourstr=0%time:~1,1%)
set datetimestr=%date:~0,4%%date:~5,2%%date:~8,2%-%hourstr%%time:~3,2%%time:~6,2%
因此，%DATE%的问题在于它依赖于区域设置。所以之前的大部分答案对我来说都不适用。如果你对确切的格式不挑剔，只是想要一个时间戳来区分文件，你可以这样做:
set _date=%DATE%-%TIME%
set _date=%_date:/=-%
set _date=%_date: =-%
set _date=%_date::=-%
set _date=%_date:.=-%
echo %_date%
这应该适用于大多数地区。如果它没有添加另一行，则设置_date=%_date:<offending_char>=-%以删除有问题的字符。例如:一个与文件名不兼容的字符或文件名中不希望出现的字符。
请注意，这并不符合问题所规定的确切标准。
