Ah...

I've been thinking "ctime" is/was (still) "create time". It seems that 
somewhere in the last couple decades it became "change time"; Or that I 
picked up that incorrect "create time" idea back in the UNIX Sys V R 3 
days and just never had cause to think about it again...

Never mind. /sigh...

What a maroon. 8-)
