Time Scale
- CURIE:
gmeow:TimeScale - IRI: https://blackcatinformatics.ca/gmeow/TimeScale
- Category: class
- Defined by:
gmeow:slices/temporal - Box roles: TBox role (What is this?)
The atomic progression of time — TAI, TT, UTC, GPS, UT1, TDB, etc. A time scale is independent of any calendar or geographic reference position.
Structure
Subclass of: gmeow:Entity, gufo:Object
Practical Pattern
Use gmeow:TimeScale as a specialized kind of gmeow:Entity, gufo:Object. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.

Usage Advice
Use when
- Use to name the underlying tick rate and epoch of a temporal frame — the answer to 'which clock', held separately from 'which calendar' and 'where'.
Avoid when
- Avoid conflating it with a calendar (Gregorian is a
gmeow:CalendarSystem, not a scale) or a timezone (gmeow:ReferencePosition); a scale is the bare physical progression, and the seeded individuals usually suffice.
How to use
- Reference a seeded scale individual (
gmeow:timeScaleUTC,gmeow:timeScaleTAI, …) from a frame viagmeow:frameTimeScale; mint a new individual, never a subclass, if a missing scale is needed.
