In Lua, you can use the built-in os.time() function to return the current time in number format.
Example:
current_time = os.time()
print(current_time)
This will return the amount of seconds that have passed since January 1, 1970.
You can also use the os.date() function to convert the os.time() value into a human-readable date and time format.
Example:
specific_time = os.time{year=2021, month=9, day=22, hour=12, min=30, sec=0}
formatted_time = os.date("%Y-%m-%d %H:%M:%S", specific_time)
print(formatted_time)
This will print 2021-09-22 12:30:00, which is the specific date and time that was specified in the os.time() function.
You can also use the os.difftime() function to calculate the difference between two times in seconds.
Example:
start_time = os.time()
-- do some work here
end_time = os.time()
elapsed_time = os.difftime(end_time, start_time)
print("Elapsed time: "..elapsed_time.." seconds")
This will print the amount of time that elapsed between the start_time and end_time values in seconds.
