RELATED EXPRESSIONS:
- 分刻み — minute by minute (also implies a very tight schedule)
- 時間刻み — hour by hour
秒刻み is hyperbolic in most everyday uses — it emphasizes that someone's schedule is extremely busy, not necessarily that every second is literally accounted for. 分刻み is more commonly used for busy schedules; 秒刻み is the more extreme version.
