What may I infer from a complaint by ftp like this:

	Y2K warning! Incorrect time-val `191000421081202' received from server.
	Converted to `20000421081202'
	221 Goodbye.

ftp said this after downloading the tarball for fetchmail 5.3.8.

May I rely on the integrity of the tarball?  Is it safe for me to use or must 
I wait until the server in question fixes its time?

For the curious, here is the full transcript:
