I think it’s important to point out the nuance. Observational winds (eg METAR) are recorded in true. Reported winds (ATIS, ASOS, AWOS) are given in magnetic. [1]
The adage goes “If you read it, it’s true. If you heard it, it’s magnetic.”
airplane inbound to land: "KXYZ tower, N12345 at 3000'

airplane: "KXYZ tower, N12345 has Romeo"
tower: "N12345, fine, but bravo is current, recommend you recheck atis"
