VirtualClock class final

A deterministic virtual clock. Never touches DateTime.now().

Constructors

VirtualClock(int seed)
Construct a clock whose epoch is deterministically derived from seed (stable across platforms: pure integer arithmetic, no wall-clock anchoring).
VirtualClock.atEpoch(int epochMs)
Construct a clock pinned to an explicit epoch (tests).

Properties

elapsedMs → int
Virtual milliseconds elapsed since the clock's epoch.
no setter
epochMs → int
final
hashCode → int

no setter
runtimeType → Type
A representation of the runtime type of the object.

Methods

advance(int ms) → int
Advance virtual time by ms (negative values are clamped to 0 — time only moves forward). Returns the new nowMs.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
