Thanks for spotting my error; it's indeed "struct tm"s that can have under-64-bit year fields. --ado -----Original Message----- From: Nicolas Alvarez [mailto:nicolas.alvarez@gmail.com] Sent: Wed 10/8/2008 5:45 PM To: tz@lecserver.nci.nih.gov Subject: RE: zdump on 64bit architectures being worked on?

As far as I know, zdump is working on 64-bit systems. Do note that time_t structures typically contain "year" elements that are less than 64 bits wide; when this is the case, very very negative and very very positive time_t values are associated with years that can't be represented using time_t's; this is why zdump shows "NULL" for these values.
You probably mean some other structure name. time_t is just a typedef for an integer type, doesn't have "year elements" :)
