Summary:                    STRFTIME returns incorrect time
Description: 
For NZ (GMT+12) function STRFTIME seems to require GMT-12 to get the date
and time right.

by example, the date and time now in NZ is 11th May 2009 , 11:27PM

Dialplan code:
exten => _9.,1,NoOp(${STRFTIME(${EPOCH},GMT-12,%Z %z %C%y%m%d%H%M)})
exten => _9.,n,Set(CallTime=${STRFTIME(${EPOCH},GMT-12,%C%y%m%d%H%M)})
exten => _9.,n,Set(CALLFILENAME=${CallTime}_${CALLERID(num)})

Console output: The Date and Time are correct. 200905112327
    -- Executing [9045609100 at outbound:1] NoOp("SIP/100-09fc4128", "NZST
+1200 200905112327") in new stack
    -- Executing [9045609100 at outbound:2] Set("SIP/100-09fc4128",
"CallTime=200905112327") in new stack

System time:

not sure that explains the "GMT-12" changing to "+1200".

The timezone offset parameter '%z' prints +1200 when timezone is set to
'GMT-12' 
In all cases, the timezone parameter '%Z' always printed "NZST"

dialplan code:
exten => _9.,1,NoOp(${STRFTIME(${EPOCH},GMT-12,%Z %z %C%y%m%d%H%M)})

printed
