WASHINGTON (AP) — Metro says some riders who used the system on the day after daylight saving time began were overcharged for their ride.

WTOP-FM reports an automatic software update was supposed to change the clocks throughout the Metro system, but it was not received at some fare gates. As a result, some riders who entered the system between 9: 30 a.m. and 10:30 a.m. Monday were charged peak fares when they should have paid off-peak rates.

Metro spokesman Dan Stessel says the problem has since been fixed. Stessel says riders who overpaid will see a credit the next time they use their SmarTrip cards.
