Currently I’m building a showcase and thought it’d be neat to have a clock that shows the user’s local time…But I’m not quite sure how I’d get the hour.
Why do I need only the hour you might ask? Well. I want to adjust the time depending on if it’s in the AM or PM. I use 24 hour time personally, but I know not everyone does so I’d like to check if the time is after 12PM, if so, it subtracts 12 from the time to get the time in PM.
If anyone can help me, that’d be much appreciated.
I’m using this in a SurfaceGui.
Code:
--ServerScript
local TimeLabel = script.Parent
function localTime(date)
local dateString = "{hour}:{min}"
local result = string.gsub(dateString, "{(%w+)}", date)
return result
end
while wait(1) do
local now = os.time()
TimeLabel.Text = localTime(os.date("*t", now))
end
local function to12H(hour)
hour = hour % 24
return (hour - 1) % 12 + 1 .. (hour > 11 and "PM" or "AM")
end
How to use it to format the current time:
local function getTime()
local date = os.date("!t")
return ("%02d:%02d %s"):format(((date.hour % 24) - 1) % 12 + 1, date.min, date.hour > 11 and "PM" or "AM")
end
-- localscript, local time, local script
local TimeLabel = script.Parent
local date = os.date("*t")
function getTime()
local hour = tonumber(date["hour"])
local minute = date["min"]
if hour > 12 then
hour = hour - 12
end
return(tostring(hour) .. ":" .. minute)
end
while wait(1) do
local now = os.time()
TimeLabel.Text = getTime()
end
@FieryEvent I don’t understand at all what you’re doing…
@Fusbot and @VineyardVine I modified and came up with this
local TimeLabel = script.Parent
local AMIndicator = script.Parent.Parent.AMIndicator
local AM = true
local function updateTime()
while wait(1) do
local now = os.time()
local Hours = os.date("*t",now)["hour"]
local Mins = os.date("*t",now)["min"]
if Hours > 12 then
Hours = Hours - 12
AM = false
AMIndicator.Text = "PM"
else
AM = true
AMIndicator.Text = "AM"
end
TimeLabel.Text = Hours .. ":" .. Mins
end
end
updateTime()
But if the minute is below 10, it shows as the number (7, instead of 07). Is that just something that happens with os.date by itself or is it something I’m doing wrong?
I can easily add code to account for that but I just don’t fully understand why it’s doing it.
And if you have any tips to improve my code that’d be helpful.
local function to12H(hour)
hour = hour % 24
return (hour - 1) % 12 + 1
end
local function getTime()
local date = os.date("*t")
return ("%02d:%02d"):format(((date.hour % 24) - 1) % 12 + 1, date.min)
end
local AMIndicator = script.Parent.Parent.AMIndicator
local TimeLabel = script.Parent
while wait(1) do
local currentHour = os.date("*t")["hour"]
if currentHour < 12 or currentHour == 24 then
AMIndicator.Text = 'AM'
else
AMIndicator.Text = 'PM'
end
TimeLabel.Text = getTime()
end
It’s just the way numbers are stored. 7 is shorter than 07, so why store it as 07? This code will fix your problem. Tell me if that doesn’t work.
You can’t have local time if you have it in the server, as the server is not local. When you said local time, I assumed you meant that you want the clock to display the local time for each player. If you want it to display YOUR local time for EVERYONE then that can be done too, but some math would have to be done to the hour to make it line up with you. If it doesn’t matter that it’s YOUR time zone, and you just want it to be local for everyone, move the SurfaceGui into StarterGui, change the script to a LocalScript, and use the Adornee property of the SurfaceGui to select the part you want it displayed on.
os.date("*t") returns the components of the current (local time if called on a localscript) in a table, such as hour and min.
Field
Type
Description
hour
int
An integer between 1 and 24 describing the current hour of the day.
min
int
An integer between 0 and 59 describing the current minute of the hour.
Because the hour is in 1-24 range instead of 0-23, we get the remainder of hour in 24 hours hour % 24, so that when hour is 24, 24 % 24 = 0. This allows us to show AM instead of PM at midnight, because 0 < 12.
% is used in lua to get the remainder.
In the 12 hour system, we want to show “12:00 PM”, instead of “00:00 AM”, we need to account to not show “00:00” and to not show “AM” when it’s midday. To do that:
Since hour % 12 (which is in 0-11 range) gives us 0 when hour is 0 or 12, we need to shift it so it gives us 12, hence: (hour - 1) % 12 + 1 (which is 1-12 range).
Since midday is included in PM, any hour after 11 AM is PM, in other words, any hour being 12 or higher is PM, hence: hour > 11 and "PM" or "AM". This expression will return “PM” if the hour is bigger than 11 otherwise “AM”.
Now to input the hour and min in the HH:MM AM/PM format we use string.format (printf):
"%02d:%02d %s"
%02d is a format specifier (%[flags][width][.precision][length]specifier ) which uses:
flags
description
0
Left-pads the number with zeroes (0) instead of spaces when padding is specified (see width sub-specifier).
so: 1:0 PM turns to 01:00 PM
width
description
(number)
Minimum number of characters to be printed. If the value to be printed is shorter than this number, the result is padded with blank spaces. The value is not truncated even if the result is larger.
