Is time ~25% faster now?

Or were all the old second counting systems wrong? Many people have pointed out that if you start a timer on your phone and count out to 45 Mississippis, hippopotamus or number-one thousands it now ties out to a minute. I have tried it a dozen times myself and after 45 counts I get anywhere between 54 to a minute and 4 seconds. I specifically remember counting chunks of time as long as 15 minutes and not being off by a minute.
