Hi,

I seem to have found a bug in the date utility, conver= ting from UTC to Sydney time. It returns invalid date for what should be= perfectly valid:

    $ TZ=3D= 'Australia/Sydney' date -d '2020-10-04T02:00:00Z'
 &n= bsp;  date: invalid date =E2=80=982020-10-04T02:00:00Z=E2=80=99
=

    $ TZ=3D'Australia/Sydney' d= ate -d '2020-10-04T02:59:59Z'
    date: inv= alid date =E2=80=982020-10-04T02:59:59Z=E2=80=99

Note DST in Sydney changed 10 hours earlier:

    $ TZ=3D'Australia/Sydney' date -d '2020-10-03= T15:59:59Z'
    Sunday 4 October  01:5= 9:59 AEST 2020

    $ TZ=3D'A= ustralia/Sydney' date -d '2020-10-03T16:00:00Z'
 &nbs= p;  Sunday 4 October  03:00:00 AEDT 2020

I have version 8.25:

Could you please report what version of tzdata you have on your system? Current on my system is tzdata version 2020b-1. And also this information too. $ zdump -v Australia/Sydney | grep 2020 Australia/Sydney Sat Apr 4 15:59:59 2020 UT = Sun Apr 5 02:59:59 2020 AEDT isdst=1 gmtoff=39600 Australia/Sydney Sat Apr 4 16:00:00 2020 UT = Sun Apr 5 02:00:00 2020 AEST isdst=0 gmtoff=36000 Australia/Sydney Sat Oct 3 15:59:59 2020 UT = Sun Oct 4 01:59:59 2020 AEST isdst=0 gmtoff=36000 Australia/Sydney Sat Oct 3 16:00:00 2020 UT = Sun Oct 4 03:00:00 2020 AEDT isdst=1 gmtoff=39600 > Note DST in Sydney changed 10 hours earlier: > > $ TZ='Australia/Sydney' date -d '2020-10-03T15:59:59Z' > Sunday 4 October 01:59:59 AEST 2020 > > $ TZ='Australia/Sydney' date -d '2020-10-03T16:00:00Z' > Sunday 4 October 03:00:00 AEDT 2020 Yes. And I think that is suspicious. Hopefully the zdump information will show that database is in need of an update and that is the root of the problem. I suspect that DST was moved at some point in time. > I have version 8.25: > > $ date --version > date (GNU coreutils) 8.25 I tried this on 8.13, 8.23, 8.26, and 8.32 and was unable to reproduce the problem on any of those versions of date. But I suspect the root cause is in the tzdata zoneinfo database.
