Lua Time

-- local getTime = os.date(“%c”);

-- %a abbreviated weekday name (e.g., Wed)
-- %A full weekday name (e.g., Wednesday)
-- %b abbreviated month name (e.g., Sep)
-- %B full month name (e.g., September)
-- %c date and time (e.g., 09/16/98 23:48:10)
-- %d day of the month (16) [01-31]
-- %H hour, using a 24-hour clock (23) [00-23]
-- %I hour, using a 12-hour clock (11) [01-12]
-- %M minute (48) [00-59]
-- %m month (09) [01-12]
-- %p either “am” or “pm” (pm)
-- %S second (10) [00-61]
-- %w weekday (3) [0-6 = Sunday-Saturday]
-- %x date (e.g., 09/16/98)
-- %X time (e.g., 23:48:10)
-- %Y full year (1998)
-- %y two-digit year (98) [00-99]
-- %% the character ‘%’

-- 如获取当前年月日时分秒：local date=os.date(“%Y-%m-%d %H:%M:%S”);

------------------------------计算时间差-----------------------------
local currentTime = os.date(os.time())
local CoolingTime = currentTime - 100

local s = os.difftime(currentTime, CoolingTime)
local str = string.format("%2d:%2d:%2d", s/(60*60), s/60%60, s%60)
print(str)

local s = os.difftime(currentTime, CoolingTime)
local str = os.date("%X", s)
print(str)

----------------------------获取指定时间值-----------------------------
-- 通过一个table参数, 指定一个时间，返回时间的数值格式
time = os.time(tab)

local tab = {year=2005, month=11, day=6, hour=22,min=18,sec=30,isdst=false}
time = os.time(tab)

-- 获取当前时间的table格式
tab = os.date("*t")

--year表示年,month表示月,day表示日期,hour表示小时,min表示分钟,sec表示秒,isdst表示是否夏令时
--tab成包括一些其他的成员 tab.yday 表示一年中的第几天 tab.wday 表示星期几(星期天为1)
