I'd like to ask that std.c.time provide the reentrant gmtime_r() function, that's available on *nix platforms. The only difference is the latter receives a destination output as an argument, rather than returning a pointer to an internal static instance; thus making it reentrant.

Without this method, one has to globally synchronize access to gmtime(). Would be nice to avoid that, especially for newbies.
