Issue ID: 19808
Summary: SysTime gives different results at compile vs. run
time execution
Product: D

import std.datetime.systime: SysTime;
import std.datetime.timezone: UTC;
static immutable ctfe = SysTime.fromUnixTime(0, UTC());
auto rtfe = SysTime.fromUnixTime(0, UTC());
assert(ctfe == rtfe); // Succeeds
string a = ctfe.toISOExtString(); // a == "1970-01-01T00:00:00+00:00"
string b = rtfe.toISOExtString(); // b == "1970-01-01T00:00:00Z"
}

Although both strings logically contain the same time information and comply
with the ISO standard, two SysTime instances comparing equal yet yielding
different strings depending on previous compile- vs. run-time execution is very
surprising.
