I read in the Developer Blog that the vami.hostname and vami.timezone properties are "built in" to Studio 2.x.
On the Output tab of VMware Studio 2.5 I do see the OVF Properties section. I want to use both the hostname and timezone properties but I'm unclear how to add them. If I click the Add.... button it prompts me for a Key. I'm all too happy to oblige, but it doesn't like it when I enter vami.hostname because it doesn't like the period.
I did look in the VMware Studio manual for awhile and really don't see coverage of this topic in there. Page 15 of the Studio 2.5 manual talks about "if the vami.hostname property is present." Not sure what it means though. If vami.hostname is "built in" then why wouldn't it be present? Thou dost vex me so.
I know I'm supposed to read between the lines here but I left my glasses at home today. 
Please assist.
Thanks,
CJ
