lua中常用时间函数有哪些

这篇文章主要介绍了lua中常用时间函数有哪些，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

-- 功能函数: 获取当前服务器时间, num型

function Player:get_cur_sys_time()

    local last = self.time_span or 0

return os.time() - last

end

-- 获取现在的日期

function CommonFunc_getNowDate()

local nd = os.date("*t", g_player:get_cur_sys_time())

return {

year = nd.year,

month = nd.month,

day = nd.day,

hour = nd.hour,

minute = nd.min,

second = nd.sec

}

end

--把服务端发过来的stme 转换为秒为单位

function CommonFunc_ConvertDateToTime(stime)

    local timeDate = os.date("*t",os.time())

    -- Log(timeDate)

    timeDate.year = stime.year

    timeDate.month = stime.month

    timeDate.day = stime.day

    timeDate.hour = stime.hour or 0

    timeDate.min = stime.minute or 0

    timeDate.sec = stime.second or 0

    -- Log(timeDate)

    print("os.time",os.time(timeDate))

    return os.time(timeDate)

end

-- 获取某年某月的天数

function UIShareToCircle:getMonthDays(year, month)

local time1 = CommonFunc_ConvertDateToTime({year=year, month=month, day=1})

-- local time1 = STime:dateToTime({year=year, month=month, day=1})

local nextYear, nextMonth = year, month + 1

if nextMonth > 12 then

nextYear = year + 1

end

return math.floor((time2 - time1)/(24*3600))

--获取同一年内，从几月几日 到几月 总共的天数

--计算从上一次登录到现在，已经几天了
