losing hardware clock time while using wvdial on usb modem


Now that I'm able to connect to internet via my MC760 wireless modem on /dev/ttyUSB0, I am losing time!
I have lost 5 minutes while online for 1/2 hr.
Yes ntpd is running. What is strange is that right now, I'm in town at coffee shop and using wireless. I'm not losing time at all. This isn't the first time I've noticed the loss of time. It's been happening every since I was able to connect with the usb modem. I just had to come to town and use wireless to see if the problem existed while on wireless (b43). While being connected via the MC760, I've also noticed that the cpu temp rises and the fan runs quite a bit more than when not connected via the MC760. Here is the top portion of output of "top"
Code:
top - 09:17:01 up  1:11,  4 users,  load average: 0.00, 0.02, 0.00
Tasks: 110 total,   1 running, 109 sleeping,   0 stopped,   0 zombie
Cpu(s):  3.7%us,  1.0%sy,  0.0%ni, 94.7%id,  0.0%wa,  0.7%hi,  0.0%si,  0.0%st
Mem:    707064k total,   391436k used,   315628k free,    18348k buffers
Swap:   683036k total,        0k used,   683036k free,   205352k cached
As you can see, not much load

uname -a shows:
Code:
Linux slacker 2.6.33.4 #1 Wed May 12 23:58:41 CDT 2010 i686 Mobile AMD Sempron(tm) Processor 3100+ AuthenticAMD GNU/Linux
I'm wondering if running a new kernel/modules might help?
This is 13.1 btw.

Any ideas?
Thanks

losing time or using data?

Are u dialup (per second / pro-rata) or gprs/edge/3g/hspda?


One wouldn't measure a bag of sugar in seconds / minutes

Don't measure a packet data connection (gprs/edge/3g/hspda) in the wrong unit!

I just lost 1 kilogram and 3 grammes of time writing this ;-P

Who is your service provider - what plan are you on - make/model of usb device (as root post output of 'lsusb')

Note to self..."how NOT to ask questions!"
I can't delete my original post so I'll probably just mark it SOLVED after I investigate some more, because I am going to use a different distro while at home and using the MC760 usb wireless modem.

However, and this probably tells a bit about my age, has anybody heard the old phrase "my watch (or clock) is losing time" or "watch is running slow. Need to wind it up"? Or perhaps heard a coach of runners/swimmers/etc say "you're losing time, pick it up!"

When I plug the MC760 in and connect to the internet, my hardware clock "loses time" or "slows down". Maybe another way to write it is that while the MC760 is plugged in and I'm online, the hardware clock on my laptop doesn't keep up with or equal real time, time on watch, or wall clock time, etc. It slows down, loses time, etc.

This happens even with ntp running.

When I get online using the MC760 with Windows, other linux distros, or OpenBSD, the hardware clock does not have the hardware clock/time problem.

Any way, nothing to do with data.

So, apologies for the original post or at least badly formed question
