[Bug-wget] using wget to mirror based on filesize only not timestamp

[Tim Lam]

Is there a way I can make wget retrieve the file based purely on filesize and 
not on timestamp.

I've tried all sorts of commands in addition to wget -m

The ftp site I want to access creates a new file everyday and gradually updates 
that file throughout the day (increasing in filesize)

Unfortunately the timestamp on the file is set to when the file was created, 
not modified

Hence whenever I use wget to mirror it see's a file that is say 6kb and 
downloads its

The next day it will see the same file and won't "redownload" the complete file 
but just skips over it, even though the file is now 19kb but the same timestamp.

Hope someone can help
