sqlite is not ruby, so you should look for a sqlite group ;)

What time?

If you want to measure execution time of a Ruby program there's Benchmark.

irb19robert@fussel:~$ irb19 -r benchmark
irb(main):001:0> Benchmark.measure { sleep 1 }
=>   0.000000   0.000000   0.000000 (  1.000137)

irb(main):002:0> Benchmark.measure { 10_000.times { |i| 10 + i } }
=>   0.000000   0.000000   0.000000 (  0.001673)

irb(main):003:0> Benchmark.measure { 1000_000.times { |i| 10 + i } }
=>   0.170000   0.000000   0.170000 (  0.170213)

irb(main):004:0> Benchmark.bm {|x| x.report("foo") { sleep 1 }}
       user     system      total        real
foo  0.000000   0.000000   0.000000 (  1.000152)
=> [  0.000000   0.000000   0.000000 (  1.000152)
]
