Java - 批處理文件試圖找到證書即將過期使用keytool

Question

我接近這..我需要得到日期數學釘下來，這是相當馬虎的權利 - 我知道。 :)

REM this is using routines from: http://www.robvanderwoude.com/datetimentmath.php 

:: Strip the day of the week from the current date 
FOR %%A IN (%Date%) DO SET Today=%%A 
:: Parse the date, prefix day and month with an extra leading zero 
FOR /F "tokens=1-3 delims=/-" %%A IN ("%Today%") DO (
    REM For European date format DD-MM-YYYY use SET Day=0%%A and SET Month=0%%B instead 
    SET Day=0%%B 
    SET Month=0%%A 
    SET Year=%%C 
) 
:: Remove excess leading zeroes 
SET Day=%Day:~-2% 
SET Month=%Month:~-2% 
:: Display the results 
SET Day 
SET Month 
SET Year 
:: Convert to Julian date 
CALL :JDate %Year% %Month% %Day% 
:: Display the result 
SET /A sdate=JDate

答：我已經想通了這一點..

有一些評論創建/使用Java程序文件要做到這一點，但是這將正常工作。
