Help?? Struct packing of Date time not has stopped working??!?!

[quickbbs at my-deja.com]

Folks,

(Please if your going to email, please email replies to
junkster at rochester.rr.com, I don't check this Deja Account, and I'm just
using it due to work's firewall)

	A strange little problem has cropped up, that I can't explain.

My Python Time server is starting to cause errors, that I believe are
server related.

In other words, the client attachs, and reports: "struct.err: str size
does not match format".

Previous to (at least) 11/30/1999, it was/is working.  But we just
noticed that the client was reporting this error today (12/14/1999).

I suspect that STRUCT isn't handling the packing of the long correctly,
as far as the manual's go, it looks AOK, but.....

Here's the server code:

#
#       Python Time Server, based off of RFC 868.

#
# Changes:
#
#	v1.0a (10/15/99)
#		- Added Logging (see logfilename)
#		- Rewrote Time Generation routine to use time.time()
#		- Increased # of default threads
#

	while 1:

		ft = timeserver_calculation()
		lt = long(ft)

		timetuple = time.localtime(time.time())
		logentry = time.strftime('%x %X', timetuple) + ' client ' +
str(addr[0]) + ' connected for timeStamp ('+str(lt)+')'

		print logentry
		logfile = open(logfilename, 'a')
		logfile.write (logentry+'\n')
		logfile.close



		conn.send ( struct.pack("!L", lt))
		conn.close()
