// Posix::time_zone tz{"EST5EDT,M3.2.0,M11.1.0"};
// zoned_time<system_clock::duration, Posix::time_zone> zt{tz, system_clock::now()};
//
// In C++17 CTAD simplifies this to:
//
// Posix::time_zone tz{"EST5EDT,M3.2.0,M11.1.0"};
// zoned_time zt{tz, system_clock::now()};
//
// If the rule set is missing (everything starting with ','), then the rule is that the
// alternate offset is never enabled.
