Some of the machines from the first production run had bad battery holders. Not the main battery, but rather the small "coin cell" battery on the mainboard that powers the time-of-day/calendar clock chip. Those battery holders have a plastic retention lip that holds the coin cell in place. On the bad ones, the lip is too small, and the batteries can become loose or even fall out entirely. When this happens, the time-of-day/calendar clock chip loses its power, forgets what day it is, and resets to the earliest date.
The long-term solution is to replace the battery holder, but I don't know what the logistics of this would be in your situation. It might involve swapping the main boards and sending the bad ones to a repair depot, or perhaps sending the entire laptop for repair, or perhaps getting a supply of the battery holders and replacing just them. As an interim solution, it might be possible to use glue to hold the coin cell battery in place. Open the laptop, insert the battery firmly in the holder, and put glue around the rim of the holder where the plastic contacts the battery, taking care not to put glue on the metal contacts. You might want to experiment with different kinds of glue that you have readily available to find on that sticks to the plastic battery holders. I am doing some experiments here. So far I have found that hot-melt glue does not work well (it doesn't stick). Solvent-based household cement seems to stick, but I haven't had time to let it harden fully. I am also trying white glue (polyvinyl acetate). I'm pretty sure that epoxy would work, because it sticks well to a lot of things, but it is slightly harder to work with than one-part glues. "Super glue" (cyanoacrylate) would probably work too, but I don't have any handy so I haven't tried it. After you have secured the battery in the holder, activate the laptop, then use the Linux "date" and "hwclock" commands to set the system date. (Or "ntpdate" and "hwclock" - see http://wiki.laptop.org/go/Customizing_NAND_images#Time) If you have developer keys for those machines and a wireless access point that is connected to the Internet, you can set the date from the firmware: ok wifi MYSSID ok ntp-set-clock where "MYSSID" is the SSID of your access point. That assumes an "open" access point. If the access point uses "WEP" security (which isn't very good), you must first set the key with: ok wep 123456789a where the argument is a 10-character or 26-character hex number. If the access point uses WPA security, you must first set the "preshared key" with ok wpa xxxxxxxxxxxx where the argument is a 64-character hex number. WPA authentication can be complicated, so it might not work for you.
