如何比较批处理文件中两个时间串

@echo off

set time1=2022-01-01 10:00:00
set time2=2022-01-01 12:00:00

REM 解析时间串
for /f "tokens=1-6 delims=- : " %%a in ("%time1%") do (
    set year1=%%a
    set month1=%%b
    set day1=%%c
    set hour1=%%d
    set minute1=%%e
    set second1=%%f
)

for /f "tokens=1-6 delims=- : " %%a in ("%time2%") do (
    set year2=%%a
    set month2=%%b
    set day2=%%c
    set hour2=%%d
    set minute2=%%e
    set second2=%%f
)

REM 比较时间
if %year1% LSS %year2% (
    echo %time1% 在 %time2% 之前

    ) else (
        if %day1% LSS %day2% (
            echo %time1% 在 %time2% 之前
        ) else if %day1% GTR %day2% (
