When you run a verbose symmask list logins there is a 'Last Active Log-In' date / time in the output:

----------------------------------------------------
symmask -sid xxx list logins -v

Symmetrix ID : 000xxxxxxxxx

Director Identification : FA-3A
Director Port : 0

Originator Node wwn : 20000000xxxxxxxx
Originator Port wwn : 10000000xxxxxxxx
iSCSI Name : N/A
ip Address : N/A
Type : Fibre
User-generated Name : 10000000xxxxxxxx/10000000xxxxxxxx
FCID : be0016
Logged In : No
On Fabric : Yes
Last Active Log-In : 08:42:07 AM on Thu Apr 10,2008
----------------------------------------------------


When a WWPN is listed as not logged in does this time give any indication as to when it logged out i.e. does the above mean that this WWPN logged out on 08:42:07 AM on Thu Apr 10,2008 or is this the last time it logged in and it subsequently logged out at some point between this time and the time the symmask command was run?

Also I assume that the date/time listed (along with dates/times listed by other symcli commands such as BCV / clone last actions) is calculated by converting some internal symmetrix time to an equivalent 'local time' based on the current time on the server running the command?
