Duration

A length of time for animation.

Partial: a duration can be authored, validated, referenced and exported. It cannot be applied to layers or mapped to a Figma variable.

Value format

{ "$type": "duration", "$value": { "value": 300, "unit": "ms" } }

Field	Allowed
value	Any finite number
unit	"ms" or "s"

In Syntope Tokens

You type	Stored as
300ms	300, ms
0.5s	0.5, s
300	300, ms. A bare number is milliseconds
{motion.fast}	A reference

In Figma

Figma layers have no property for a duration, so Apply token is disabled for this type. Variable sync leaves duration tokens out.

Use durations in code through export or sync, and inside a transition token.
