Converting GTimeVal value to Gdate struct

[sam <sam028 free fr>]

Hi all.

I'm trying to convert my GTimeVal values (in GTimeval.tv_sec) in a GDate 
struct, or a string like YYYY/MM/DD-HH:MM:SS. I found the g_date_to_struct_tm 
function, wich convert a GDate variable to an struct tm variable, but I need 
the opposed function (tm to GDate).

Any idea ?

Sam.

ps: is there any GLib mailing list ? My question is maybe not appropriate 
here ...
