High-Resolution Chronometry & Event Loop Timing
Standard browser intervals can drift significantly under CPU load. This chronometer eliminates cumulative timer drift by referencing absolute epoch timestamps at every render tick.
1. Drift-Compensated Elapsed Master Time
T_elapsed=Date.now() − t_origin (ms)
2. Lap Interval Delta Formula
Δt_lap(k)=T_split(k) − T_split(k−1)
Step-by-Step Chronometer Breakdown (Example: 3-Lap 400m Track Run)
Step 1: Record Lap 1 (00:00.00 to 01:14.20)
Lap 1 Duration = 01:14.20 | Master Split = 01:14.20
Step 2: Record Lap 2 (Master Clock at 02:26.50)
Lap 2 Delta = 02:26.50 − 01:14.20 = 01:12.30 (Fastest Lap)
Step 3: Calculate Mean Lap Pace
Average Pace=Total Time / Total Laps=01:13.25 / Lap
