This is a useful field to know when the last time the server talked to the handheld... until I started to suspect this information, as there were contact times very recently with handhelds that I knew were disabled.
To test this out I turned off my BlackBerry and restarted the BES task. The last handheld contact time updated to the current time, with the device turned off in front of me! See the below screenshot, showing last contact time of 1/15/2008 10:16:51AM, when the device was turned off at about 10:10 AM.
To see why this is updating, I checked the MAGT logs for activity on my account during this time:
[40000] (01/15 10:16:51.733):{0xB04} {Test User/Domain} Sending PIM Transaction to Sync Server, Tag 225 (config request)
[40000] (01/15 10:16:51.733):{0x1F9C} [BIPP] Send data, Tag=225
[40000] (01/15 10:16:51.748):{0x19E0} [BIPP] Received status DELIVERED, Tag=225
[40392] (01/15 10:16:51.748):{0xB04} {Test User/Domain} SRP: TID=225, type PIMSYNC returned DELIVERED
[40000] (01/15 10:16:51.748):{0x19E0} [BIPP] Received datagram, Tag=436
[40076] (01/15 10:16:51.748):{0xB04} {Test User/Domain} SendStatusToWirelessNetworkUsingSRP SendQ, TID=436
[40400] (01/15 10:16:51.748):{0xB04} {Test User/Domain} Received datagram with content type agent_sync, TID=436, for user Test User/Domain
[40000] (01/15 10:16:51.748):{0x1F9C} [BIPP] Send status DATA_ACCEPTED, Tag=436
The only activity that occured was an internal communication to the Sync server, and what looks like a request to perform a handheld agent sync. Note that both transactions appear to show successful connections with the device, however these are only internal communications between components on the BES server itself. Perhaps the time of successful internal communication is being reported?
In any case, it appears that this is quite a bogus field which provides no useful real world information.

I would be interested to know if the MAGT log contained a "Last HH Contact" time that corresponded to the "Last Contact Time" in your screenshot.
I am trying to determine if a Blackberry is in use (whether use means simply switched on or more than that) and I thought the Last HH Contact field in the MAGT log might be a good starting point.
