Some Philadelphia FM Station is sending incorrect RDS time signals
I haven't check recently here in the DC area, but a couple of years ago only
about 25% of the RDS stations were as close as 30 minutes to the correct
time. 99.5 used to be really accurate, but they were sending GPS correction
signals at the time. That is no longer true.
The West Va State Network was an hour off during the summer. Their RDS
clocks had to be manually set at each transmitter, and that would have meant
many hundreds of miles of driving. So they left them on standard time [EST]
all year.
I don't think you can expect any improvement unless stations put more
emphasis on RDS. Sadly, dropping RDS seems to be more common around here.
