It has switches and circuitry to set the time. Presumably he sets it for daylight savings changes, at the very least. And the page says it was turned off at least twice. It's not meant to keep a perfectly accurate count of time over 40+ years.
However, it must be by several seconds out by now. There were several 'leap seconds' introduced since 1970.
