Os.date()

Feature Requests Engine Features
#1

Hey there,

I would love to use os.date() on ROBLOX, so that we can create calendars and automatic systems that will work by date :slight_smile:
We can also do time stamps on date this way.

Example :

  • A ModuleScript that will make the entire game ready for Christmas
  • A Shop that will have daily dails
  • A Shop that will have ‘summer’ deals, when it is truely summer.
  • A Shop that will have ‘weekly’ deals

Script that performs action while servers are closed

Before any of you start that this is already possible with Math :

  • Yes, it is. But it is a pain in the butt to have all those exceptions.

os.date() would be a nice thing to have – it’s fairly annoying to have to convert seconds to date when all you want is mm:dd:yyyy e.e

I wonder why .date() was removed from os in the first place as well.

#4

wait how do we use math to get the date?

months = {"January","February","March","April","May","June","July","August","September","October","November","December"}
daysinmonth = {31,28,31,30,31,30,31,31,30,31,30,31}

function getDate()
	time = os.time()
	local year = math.floor(time/60/60/24/365.25+1970)
	local day = math.ceil(time/60/60/24%365.25)
	local month
	for i=1, #daysinmonth do
		if day > daysinmonth[i] then
			day = day - daysinmonth[i]
		else
			month = i
			break
		end
	end
	
	return month, day, year
end

local month, day, year = getDate()
root.CompletedTasks.CurrentDate.Text = "Today's Date is: "..month.."/"..day.."/"..year

Straight off of free models – readily available to all.

Using os.time to make a multiple textboxes show Years, Months, Days, Hours, Minutes, and Seconds?

@Echo.
The math behind it isn’t really accurate. Leap years for example aren’t done in that code :wink:
And I really don’t understand why we have os.time() and os.difftime() and not os.date()

I wouldn’t expect any better – it was on free models. :wink:

I’m with you on that one.

Is there an easily-accessible API that you can read the month/day/year from somewhere out there (using HTTPService)? Anyone who could take that and make it into a script would be a hero!

#9

Could just grab it off of this site

#10

It won’t be accurate since time is taken for the HTTP request to reach both ends.

Could just grab it off of this site[/quote]Any clue how? I’m a total noob to HTTPService, so…

#13

Guys. I’m aware that this is possible using HTTPService, but could we please have it in ROBLOX without HTTPService…

I would rather have some TimeToDate function that takes a unix time argument and returns a tuple of the date values (seconds, minutes, hours, etc.). This way we can get the date of arbitrary times.

Ahahahahahaha XD[/quote]

That’s not a helpful post at all. Making fun of people for asking legitimate questions isn’t okay IMO.

Here, I made something simple. It takes two arguments: Timezone and Pattern.
Use this to construct patterns based on PHP’s date()

Example:
http://osyrisrblx.com/date.php?Timezone=EST&Pattern=Y-m-d%20H:i:s

So to get that in ROBLOX you’d do something in Lua like…

local DateString=game:GetService("HttpService"):GetAsync('http://osyrisrblx.com/date.php?Timezone=EST&Pattern=Y-m-d%20H:i:s')

Don’t use ‘date()’ - use ‘gmdate()’ (I think that’s the function) - ‘gmdate()’ returns what ‘os.time()’ would in Lua.

Good timing! My timestamp() function stopped working recently (badly coded, but lasted 2 years), so I started writing a new one. Little did I know it would take me 5 hours. Christ. I have no idea, I was much better when I was 15. If it’s ever taking you that long to do something, stop, take a break and rethink. I wasted too much time.

EDIT: Forgot to mention, IT SUPPORTS LEAP YEARRRSSSSS!!

But here it is: (sorry if it’s hard to read I have a blue theme to “keep me” cool, I hate the Summer heat.)

And the code, change the timezone to your liking. I live in EST.

function getMonth(DoTy, months)
	local var2 = DoTy
	for i = 1, #months do
		if var2 <= months[i] then return i, var2 else var2 = var2 - months[i] end
	end
end

function timestamp()
	local months = {31, 28, 31, 30, 31, 30, 31,31,30, 31, 30, 31}
	local timezone, offset_hours = "EST", -4
	local secondspassed = os.time()+(3600*offset_hours)
	local yearspassed = math.floor(secondspassed/31557600)
	local YoTc = yearspassed-30 -- Year of the Century (change the 30 to 130 when it's 2100 :D (if it's 2100....))
	local DoTy =  math.floor((secondspassed-(yearspassed*(31557600)))/86400)+1
	if YoTc/4-math.floor(YoTc/4) == 0 then months[2] = 29 end
	local MoTy, DoTm = getMonth(DoTy, months)
	local HR = math.floor((secondspassed-((math.floor(secondspassed/86400))*86400))/3600)
	local MIN = math.floor((secondspassed-((math.floor(secondspassed/3600))*3600))/60)
	local SEC = math.floor((secondspassed-((math.floor(secondspassed/60))*60)))
	if string.len(HR)==1 then HR = "0"..HR end
	if string.len(MIN)==1 then MIN = "0"..MIN end
	if string.len(SEC)==1 then SEC = "0"..SEC end
	return MoTy.."/"..DoTm.."/"..YoTc..", "..HR..":"..MIN..":"..SEC.." "..timezone..", Day of the Year: "..DoTy
end
