    • temp = { 546775200, 976708800, 1578657600 }

CODING EXAMPLE:

-- Include/Call for this library
require("date")
temp = date.date_to_seconds(t) --see table t above
for a,b in ipairs(temp) do print(b) end
--546775200 
--976708800
--1578657600

seconds_to_date

INPUT:
This library function required the following inputs/parameters.

  • Table of seconds since 1970
    • Example: t = { 546775200, 976708800, 1578657600 }

OUTPUT:
This library function deliverers the following output/parameters.

  • Will give a table with a formated string
    • temp = { {Thu Apr 30 10:00:00 UTC 1987}, {Wed Dec 13 12:00:00 UTC 2000}, {Fri Jan 10 12:00:00 UTC 2020} }

CODING EXAMPLE:

-- Include/Call for this library
require("date")
temp = date.seconds_to_date(t) --see t above
-- the formated string is found in the top of date.lua 
-- is format = "%a %b %d %X %Z %Y"

date_diff

INPUT:
This library function required the following inputs/parameters.

  • Two dates as seconds to difference
    • Example: (546775200, 976708800)
      • Thu Apr 30 10:00:00 UTC 1987, Wed Dec 13 12:00:00 UTC 2000

OUTPUT:
This library function deliverers the following output/parameters.

  • A table
    • temp = { min=0, day=17, month=8,sec=0,hour=2, year=13}

CODING EXAMPLE:

-- Include/Call for this library
require("date")
temp = date.date_diff(546775200, 976708800)
--temp will be valued as above. This will not be completely accurate in relation to leap years...
