Thank you.  I want to work in strings, so the first one's not an 
option.  But both the second and third do the trick.  Would you 
say the to!string would be the most idiomatic?  It worked as 
"to!string(ctime(&t))", but is it safe to assume it's reliably 
dealing with null-terminated strings?  It's the pithiest if so.
