<E, R>(ref: RefDateTime<E, R>, parts: Partial<{
readonly millis?: number;
readonly seconds?: number;

};Why
Subtract a Duration from the current state of a RefDateTime. The operation remains attached to the RefSubject’s versioned state boundary.
Ownership and lifetime
The subtract view retains no independent state. An Effect read samples the source once; Fx observation follows later pushes and its observing Scope owns subscription cleanup.
Other public imports
These import paths expose the same declaration. Each page retains its own public name and signature.
