*** Update 11/27/2014 - It was asked in the comments if this applies to the Lync Phone Edition devices (LPE). LPE is created/maintained by Microsoft but various companies manufacture the devices, including Polycom. The Polycom LPE’s are the CX series phones. This article does not apply to the LPE devices. It only applies to the Polycom phones that run Polycom’s own software such as the VVX line of phones.

Lately, I have found myself having to do the math for the time offset for DHCP Option 002. I decided it was worth just documenting them so I could look them up quickly and what better way to come up with all of them than with Powershell?
