lua脚本编写后天数的日期

我是lua脚本的新手.我有一个startDate(“03-05-2014”作为“dd-mm-yyyy”)和几天的跨度(2)任何人都可以帮助我如何根据startDate和span获得endDate？

Example startDate     span            endDate 
        ---------     ----            -------
        03-05-2014     2             05-05-2014
       (dd-mm-yyyy)                 (dd-mm-2014)

这可以帮到你

local dayValue, monthValue, yearValue = string.match('31-05-2014', '(%d%d)-(%d%d)-(%d%d%d%d)')
dayValue, monthValue, yearValue = tonumber(dayValue), tonumber(monthValue), tonumber(yearValue)
now = os.time{year = yearValue, month = monthValue, day = dayValue}
numberOfDays = now + 2 * 24 * 3600
print(os.date("%c",numberOfDays))
dateAfterNumberOfDays = os.date("%a %d %B %Y, %H%p%M",numberOfDays)
print ("\nafter number of days "..dateAfterNumberOfDays) -- give you date after number of days
