Use os.time()...
Programming in Lua : 22.1

Yes, with os.time() but im not sure exactly how it should be coded.

For what you wanna use it, maybe it can be done differently.

Post the server version.

See a bunch of useless posts in this thread, if you're not helpful just don't post lol.
Anyway, I believe there should be a better way to do it, but here's my attempt:

function timeForHour(hour)
    local time = (string.split(hour, ":")[1]*60) + string.split(hour, ":")[2]
    local current = (os.date("%H")*60) + os.date("%M")
    local diff = current < time and time - current or 1440 - (current - time)
    local hr = math.floor(diff / 60)
    local format =hr .. ":" .. math.floor(diff - (hr * 60))
    return format
end

Testing:

print("Current: " .. os.date("%H:%M"))
print(timeForHour("2:27") .. " hours left until its 2:27")
print(timeForHour("12:40") .. " hours left until its 12:40")
print(timeForHour("14:45") .. " hours left until its 14:45")
print(timeForHour("1:31") .. " hours left until its 1:31")

Output:

Current: 14:43
11:44 hours left until its 2:27
21:57 hours left until its 12:40
0:2 hours left until its 14:45
10:48 hours left until its 1:31

Thanks Bogart
Could you add seconds too?

function timeForHour(hour)
    local time = (string.split(hour, ":")[1] * 60 * 60) + (string.split(hour, ":")[2] * 60) + string.split(hour, ":")[3]
    local current = (os.date("%H") * 60 * 60) + (os.date("%M")*60) + os.date("%S")
    local diff = current < time and time - current or 86400 - (current - time)
    local hr = math.floor((diff / 60) / 60)
    local mi = math.floor(math.floor(diff - (hr * 60 * 60)) / 60)
    local se = math.floor(diff - ((mi * 60) + (hr * 60 * 60)))
    local format = hr .. ":" .. mi .. ":" .. se
    return format
end

timeForHour("HH:MM:SS") --> "HH:MM:SS"
