'head' font creation date

[jeremie]

Hello,

Apologies for double post in Robofab list.

In FontLab I want  to set the 'head' table font creation date through a Python script.
the command:
>>print f.ttinfo.head_creation
gives
>>[-975435447,0]

Robofab ObjectsFL library also stuck on this intriguing output, and comments:
# ttinfo.head_creation has an unknown format
and
# XXX how should this be set?

Does anyone know how ttinfo.head_creation should be set?

I am also interested to know what format this is. From what I've been experimenting with, it seems to be dependent on both the Unix and NTP epochs. Any help, FontLab?
