Ticketer: improve consistency when editing

[gpotter2]

• some timezones are dropped when editing a ticket, fix that
• padding was not like on Windows when building the UPN PAC structure
• CLIENT_INFO should be the same timestamp as the outer kerberos authtime. Make sure of that when resigning, else there might be an error related to "message integrity"
