I understood from the comments in DJGPP's ctime.c that the source is from BSD. Therefore, I consulted the correspondant file from the FreeBSD source code, that is contrib/tzcode/localtime.c : https://svnweb.freebsd.org/base/stable/9/contrib/tzcode/stdtime/localtime.c?view=markup In that file: - the stdoffset variable is set explicitly to zero (second modification in the patch) and - the defaulttype attribute is not defined, but its value is calculated every time. Thank you and best regards, -- Arrigo
