コントラクト
- assert Carbon modifier methods like startOfDay() and endOfDay() mutate instance in place while CarbonImmutable returns isolated new instances
- assert createFromFormat('Y-m-d') inherits current execution wall-clock time unless reset with '!' prefix or '|' suffix to 00:00:00.000000
- assert addMonth() on month-end dates overflows into March unless addMonthNoOverflow() is explicitly used to clamp to February end
- assert diffInDays() in Carbon 3 returns signed float with fractional days by default rather than positive integer
- assert setTimezone() converts instant altering wall-clock hours while shiftTimezone() preserves wall-clock hours with updated offset
- assert embedded timezone offset in parse() payload overrides explicit timezone argument
