:: 判斷一個(gè)腳本執(zhí)行完畢所需要的時(shí)間
:: 先取開(kāi)始時(shí)間，然后在即將結(jié)束的時(shí)候取結(jié)束時(shí)間
:: 兩個(gè)時(shí)間都分別提取小時(shí)、分和秒數(shù)
:: 分別對(duì)小時(shí)數(shù)、分鐘數(shù)和秒數(shù)進(jìn)行操作
:: 還要對(duì)08和09這兩個(gè)數(shù)進(jìn)行操作
:: 注意：set /a num=的格式只能處理兩位數(shù)中是否高位為0，如果是多位數(shù)
::       要去高位的所有0的話，要用循環(huán)測(cè)試高位是否為0或者在高位添1然后
::       再減去1000之類的數(shù)字的方法
