>From code I found that, when a TGT is fetched from KDC, the cache header
stores times_offset based on the authtime of the ticket. Looks like you can
also store usec_offset in the cache header. But I haven't seen any code
setting the same.


Can anyone help me to understand 

1.       Why this header is needed ?

2.       When the values times_offset and usec_offset are set?

3.       When the values set in header are used?
