In DMD Version 2.043, the following code should print a timestamp both
in UTC and local time. The local tzoffset is correct, but the UTC
tzoffset should not be nonzero. Furthermore, what claims to be the UTC
time is actually the localtime, and the so-called localtime is just
wrong. The code imports std.datebase to hack around the initialization
issue reported in #2965.

    #!/usr/bin/dmd -run

    import std.datebase;
    import std.stdio;
    import std.date;

    void main() {
        writefln("UTC:   %s", toString(getUTCtime()));
        writefln("Local: %s", toString(UTCtoLocalTime(getUTCtime())));
    }
