In Julia, you can use the times() function to get the current system time in seconds, with high resolution. This function returns a floating-point number representing the number of seconds since the system clock’s epoch time.
Here is an example code snippet showing how to use times() in Julia:
# Get the current system time
t1 = times()
# Run some code here
x = 0
for i in 1:10^6
x += i
end
# Get the current system time again
t2 = times()
# Compute the elapsed time
elapsed_time = t2 - t1
println("Elapsed time: $elapsed_time seconds.")
In this example, we first call times() to get the current system time in seconds, and store it in the variable t1. Then, we run some code that takes some time to execute, which just sums up the numbers from 1 to 1 million. Finally, we call times() again to get the current system time in seconds, and store it in the variable t2. We subtract t1 from t2 to get the elapsed time, and print out the result.
Keep in mind that the actual resolution and precision of times() may vary depending on the system and the hardware being used.
