A sentence I read on Wikipedia today:

On 30 April 2015, the U.S. Federal Aviation Administration announced it will order Boeing 787 operators to reset its electrical system periodically, to avoid an integer overflow which could lead to loss of electrical power and ram air turbine deployment, and Boeing deployed a software update in the fourth quarter. The European Aviation Safety Agency followed on 4 May 2015. The error happens after 2^31 hundredths of a second (about 249 days), indicating a 32-bit signed integer.
