How to profile run time on card?

[feature]

I want to find out how much time each line takes so that I can optimize my application.
I created a log class which I can write and read to, but I can't find any way to measure time... I see that JCop 3.1 has a javacardx.framework.time package which seems to have what I need - but my card only supports 3.0.5.

Is there any way to log durations in JCop 3.0.5 or 2.2.2?

JavaCard 3.0.5 and earlier versions like 2.2.2 do not include the javacardx.framework.time package, which means you can't directly measure time using built-in APIs papa's games
