Thank you for the in depth analysis. We are good for now.  Sent from Yahoo Mail for iPhone On Friday, August 26, 2022, 12:10 PM, Paul Eggert <eggert@cs.ucla.edu> wrote: On 8/26/22 10:06, W CUI wrote:

Fine, but Solaris 10 /usr/bin/date is a 32-bit executable and is dynamically linked to a 32-bit C library /lib/libc.so.1 that is reading your TZif files. Presumably your "isainfo -v" outputs something like this:   64-bit sparcv9 applications         vis2 vis   32-bit sparc applications         vis2 vis v8plus div32 mul32 and the last two lines are what matter here. I expect that 64-bit Solaris 10 apps don't have this problem. To find out whether I'm right, you can run '/usr/bin/sparcv9/ls -l' on a new file and look at the resulting timestamp. Regardless, if this issue is a real problem for you then it's time to file a bug report with Oracle (you can tell them I sent you :-). And in the meantime you can get by with 'zic -b fat'.
