FAMS is a secret interface. IBM may or may not provide the
documentation upon receipt of a signed NDA, and presumably, a "nominal" fee.

A Google search for FAMS returns the NFS reference, a SHARE presentation, a RFE,

Where is this thing documented? It should be useful.
Also, from the NFS Guide:
... The server uses the following main time stamp sources to generate
UNIX time stamps for MVS z/OS conventional (legacy) file systems:
DSCB (data set control block)
Master Catalog data set attribute extension (AX) cell
PDSE member attribute extension (AX) cell
ISPF member statistics
TOD (current time_of_day on the server side).
