Right. 'info' returns the time in UTC.
I think it would be too much trouble to change 'info' or write a similar
function in C.
I would recommend to write a function that calculates the offset of the
current time zone. You could, for example, parse the output of the
'date' command like
: (in '(date "+%:z") (line))
-> ("+" "0" "2" ":" "0" "0")
or
: (in '(date "+%z") (read))
-> 200
but I think it is more efficient to call the built-in 'date' function
twice, once without arguments to get the local time, and once with 'T'
to get UTC. Then round the difference to compensate for a possible time
lag between these two calls.
(de tzOffset () # Return the time zone offset in seconds
(* 60 # Round to whole minutes
(*/
(- # The difference of
(+ (* 86400 (date)) (time T)) # local time in seconds
(+ (* 86400 (date T)) (time T)) ) # and UTC in seconds
60 ) ) )
Then you could output the desired file date in local time in this way
: (when (info "CHANGES")
(let Tim
(+
(+ (* 86400 (cadr @)) (cddr @))
(tzOffset) )
(stamp (/ Tim 86400) (% Tim 86400)) ) )
-> "2008-04-23 18:29:06"
Cheers,
