crazy electical question

["Dave Caroline" <dave.thearchivist@gmail.com>]

If its a mains counting clock then its getting interference when on
that outlet. Sources of interference are for example loose
connection/arcing or a light dimmer on the same circuit or an arcing
commutator on a motor or failed suppression in some device etc. Have
the outlet checked. Listen to mw radio near the outlet for electical
noise
