How to use the Time package in Lua programming?
Lua library provides us with a time package that can be used to calculate the current time and that current time can be converted into hours, days and minutes and we can also take the later values and turn them into a Lua representation of time.
In order to make use of the library time package, we don’t necessarily need to require anything, we just need to write the following command in a Lua script and we are done.
Lua code for printing the current time in Lua format −
Example
print(os.time())
Output
1624642168
The output of the above time command definitely isn’t something that we normally expect when we talk about time, but this is how lua represents time, the number returned is basically a coded number which is a combination of current date and time.
Example
Now that we know how to print the current coded date and time number, let’s encode it and convert it into hours and seconds.
Consider the code shown below −
local date = os.time() local day2year = 365.242 -- days in a year local sec2hour = 60 * 60 -- seconds in an hour local sec2day = sec2hour * 24 -- seconds in a day local sec2year = sec2day * day2year -- seconds in a year -- year print(date // sec2year + 1970) --> 2021.0 -- hour (in UTC) print(date % sec2day // sec2hour) -- minutes print(date % sec2hour // 60) seconds print(date % 60)
Output
2021.0 17 33 9
