Case
- Goal
- Preserve custom timestamp and sequence options in UUIDv7 generation instead of silently discarding msecs to epoch zero HOW
- Packages
- uuid 11.1.1
- Environment
- node
- Created
- 2026-08-16T07:08:08Z
Contract
- assert v7({ msecs }) encodes the exact 48-bit timestamp into UUID bytes 0..5
- assert v7({ msecs }) produces a valid RFC 9562 UUID with version 7 without zeroing timestamp to 1970 epoch
- assert v7({ msecs, seq }) preserves user-supplied timestamp and sequence values
- assert v7() without options maintains monotonic ordering and isolates state from explicit-options calls
