将Powershell合并到一个批处理文件中，并使用元变量来分配每个:

@echo off
for /f "tokens=1-6 delims=-" %%a in ('PowerShell -Command "& {Get-Date -format "yyyy-MM-dd-HH-mm-ss"}"') do (
    echo year: %%a
    echo month: %%b
    echo day: %%c
    echo hour: %%d
    echo minute: %%e
    echo second: %%f
)

如果您更喜欢月份名称MMM或MMMM以及12小时到24小时格式hh或hh，您也可以更改格式

生成ISO日期格式的区域独立解决方案:

rem save the existing format definition
for /f "skip=2 tokens=3" %%a in ('reg query "HKCU\Control Panel\International" /v sShortDate') do set FORMAT=%%a
rem set ISO specific format definition
reg add "HKCU\Control Panel\International" /v sShortDate /t REG_SZ /f /d yyyy-MM-dd 1>nul:
rem query the date in the ISO specific format 
set ISODATE=%DATE%
rem restore previous format definition
reg add "HKCU\Control Panel\International" /v sShortDate /t REG_SZ /f /d %FORMAT% 1>nul:

还有什么可以优化的: 如果在修改日期格式的短时间内使用日期格式，其他进程可能会感到困惑。因此，根据现有的格式字符串解析输出可能会“更安全”——但会更复杂

这是我使用的:

::Date Variables - replace characters that are not legal as part of filesystem file names (to produce name like "backup_04.15.08.7z")
SET DT=%date%
SET DT=%DT:/=.%
SET DT=%DT:-=.%

如果你想进一步的想法自动备份到7-Zip档案，我有一个免费/开放的项目，你可以使用或审查的想法:http://wittman.org/ziparcy/

在Windows 7中，这段代码适用于我:

SET DATE=%date%
SET YEAR=%DATE:~0,4%
SET MONTH=%DATE:~5,2%
SET DAY=%DATE:~8,2%
ECHO %YEAR%
ECHO %MONTH%
ECHO %DAY%

SET DATE_FRM=%YEAR%-%MONTH%-%DAY% 
ECHO %DATE_FRM%

这是时间部分的类似批处理文件。

:: Works on any NT/2k machine independent of regional time settings

:: Gets the time in ISO 8601 24-hour format
::
:: Note that %time% gets you fractions of seconds, and time /t doesn't, but gets you AM/PM if your locale supports that.
:: Since ISO 8601 does not care about AM/PM, we use %time%

    @ECHO off
    SETLOCAL ENABLEEXTENSIONS
    for /f "tokens=1-4 delims=:,.-/ " %%i in ('echo %time%') do (
      set 'hh'=%%i
      set 'mm'=%%j
      set 'ss'=%%k
      set 'ff'=%%l)
    ENDLOCAL & SET v_Hour=%'hh'%& SET v_Minute=%'mm'%& SET v_Second=%'ss'%& SET v_Fraction=%'ff'%

    ECHO Now is Hour: [%V_Hour%] Minute: [%V_Minute%] Second: [%v_Second%] Fraction: [%v_Fraction%]
    set timestring=%V_Hour%%V_Minute%%v_Second%.%v_Fraction%
    echo %timestring%

    :EOF

我使用date.exe，并将其重命名为date_unxutils.exe以避免冲突。 把它放在批处理脚本旁边的bin文件夹中。

Code

:: Add binaries to temp path
IF EXIST bin SET PATH=%PATH%;bin

:: Create UTC Timestamp string in a custom format
:: Example: 20210128172058
set timestamp_command='date_unxutils.exe -u +"%%Y%%m%%d%%H%%M%%S"'
FOR /F %%i IN (%timestamp_command%) DO set timestamp=%%i
echo %timestamp%
