Hi,

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

    $ TZ='Australia/Sydney' date -d '2020-10-04T02:00:00Z'

    date: invalid date ‘2020-10-04T02:00:00Z’

    $ TZ='Australia/Sydney' date -d '2020-10-04T02:59:59Z'

    date: invalid date ‘2020-10-04T02:59:59Z’

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

I have version 8.25:

    $ date --version

    date (GNU coreutils) 8.25
