A New Haven parking garage got busted after an investigation showed that the entry clock was set four minutes slow, while the exit clock was set five minutes fast, resulting in patron after patron getting overcharged. After investigators alerted the garage, a spokesperson said they know of the “timing synchronization concerns” and promised to check them out and fix them if they found any “discrepancies.”
