In Virtual PC:
Changing the BIOS date in virtual PC can be done very easily by entering the emulated BIOS. However, to make it keep that date after a reboot, you need to edit your vmc file.

1. Locate your .vmc file, and open it in notepad. Make sure Virtual PC is closed so you can save your edited file.

2. As you can see, its a standard XML file. All you need to do is insert

Code:

<components>
   <host_time_sync>
      <enabled>false</enabled>
   </host_time_sync>
</components>

Inside the <integration> and <microsoft> tags, like shown below:

3. You can now change your time and date in the emulated bios, and now the clock should not revert to the host time after a reboot.

In VMWare
Open your .vmx configuration file. All you need to do is place the following lines of code anywhere in this text file.

Code:

tools.syncTime = "FALSE"
time.synchronize.continue = "FALSE"
time.synchronize.restore = "FALSE"
time.synchronize.resume.disk = "FALSE"
time.synchronize.shrink = "FALSE"

If you have any problems, place them below.

Thx man, that's very useful, I will give a try later :]

I have tested it and it works on my end.
You only need this code:

Quote:

Code:
<components>

<host_time_sync>

<enabled>false</enabled>

</host_time_sync>

</components>

And dont need the:

Code:

Type ="boolean"

otherwise my virtual pc doesnt boot any more.

Thanks

This depends on the version of Virtual PC that you're using...

It should be enough to change the date in the VM's BIOS (you know how to enter that, do you?) and to disable the time sync feature in VMware's preferences.

I had to edit the configuration (.vmx) file and place the following at the bottom:

Code:

tools.syncTime = "FALSE"
time.synchronize.continue = "FALSE"
time.synchronize.restore = "FALSE"
time.synchronize.resume.disk = "FALSE"
time.synchronize.shrink = "FALSE"

Adding this to the first post

sorry for bumping the thread.

But the trick doesn't work for Virtual PC 2007. I've insert the entry with and without type="boolean", but the Date is always set to the current date

Rob Jansen · **Post subject:** **Posted:** Wed Oct 31, 2007 2:58 pm

Then your VPC 2007 is not good.
Its works.
With the boolean insert.

But have insert it in the right place?

hounsell · **Post subject:** **Posted:** Wed Oct 31, 2007 3:05 pm

For me, with the type="boolean" works in Virtual PC 2007.

Luckie · **Post subject:** **Posted:** Wed Oct 31, 2007 4:07 pm

I forgot to close the <components> tag :oops:

now it seems to work.

Cheers for this. Having to snapshot/restore was getting rather annoying.

Hi,

Just joined here. I have Virtual PC 2007 and did what you said to change the BIOS date on it, so I tried it but for some reason cannot change the day number, I can change the month and year but not the day, anyone know why?

Anyone have a utility to do this automatically in VMWare?

TheCollector1988

on VMware it is very easy as doing Virtual PC's
