std::gmtime() has a sad property of using a global static buffer for returning its value. This is not thread-safe, so its usage is replaced with gmtime_r, which can accept a local buffer. While no regressions where observed in this particular area of code, a similar bug caused failures in alternator, so it's better to simply replace all std::gmtime calls with their thread-safe counterpart.
