Looking at the tnfdump display, you can see how long it takes to find a factor by subtracting the factor_start time from the factor_end time. Factoring 43645729 took 208857.960000 - 108271.852000, or 100586.11 milliseconds. Factoring 12 took 334511.808000 - 334511.548000, or .260000 milliseconds.
Results are reported with nanosecond precision for all hardware platforms. Accuracy, however, depends on the hardware platform used.
