Subject: [PATCH 07/19] TestDateTime: fix GetAsStringsWithBias and add Tzdata
 tests

The 'GetAsStringsWithBias' test logic assumed the timezone on
machine bullding Kodi is set to 'UTC'. This is not always the case,
plus hour value was declared with a typo.

To address this, we compare outputs of two runs of date library,
and instead add a 'Tzdata' test case comparing local date and time
against computed values from different timezones:

find /usr/share/zoneinfo/Etc/ -type f | sort -Vu | sed 's,^/usr/share/zoneinfo/,,' | while read TZ
do
  TMSTR=$(LANG=C TZ="$TZ" date '+%Y-%m-%dT%H:%M:%S%Ez' -d "1991-05-14 12:34:56 UTC" | sed 's/[0-9][0-9]$/:&/')
  echo "  // LANG=C TZ=\"$TZ\" date '+%Y-%m-%dT%H:%M:%S%Ez' -d \"1991-05-14 12:34:56 UTC\" | sed 's/[0-9][0-9]$/:&/'"
  echo "  tps = date::floor<std::chrono::seconds>(dateTime.GetAsTimePoint());"
  echo "  zone = date::make_zoned(\"$TZ\", tps);"
  echo "  EXPECT_EQ(date::format(\"%FT%T%Ez\", zone), \"$TMSTR\") << \"tzdata information not valid for '$TZ'\";"
  echo ""
done

Subject: [PATCH 08/19] Remove GetAsUTCDateTime and add GetAsLocalDateTime

The 'm_time' now represents a UTC time-point, so 'GetAsUTCDateTime'
does nothing useful. Remove it fully, and add 'GetAsLocalDateTime'
function that we will use later to convert UTC (system) time to the
local time needed to get displayed in UI.

Subject: [PATCH 09/19] Compensate the representation change

... from local time by default to UTC time by default.

Namely, 'CDateTime::SetFromUTCDateTime' converted the UTC time
to local time in the implementation of CDateTime before
'std::chrono'. Now this conversion has gone, and to avoid
displaying PVR times in UTC, 'GetAsLocalDateTime' is added
where necessary.

From aa67f78a15516a6c5643f36c15bfc1eebe07f172 Mon Sep 17 00:00:00 2001
From: Vasyl Gello <vasek.gello@gmail.com>
Date: Wed, 4 Nov 2020 11:13:15 +0200
Subject: [PATCH 10/19] Get rid of {Set,}FromUTCDateTime

  * The 'const CDateTime& CPVRRecording::RecordingTimeAsLocalTime() const'
    method needs 'static' CDateTime instance set explicitly. This manifested
    in Debian Bug #980038 : the return value of function is explicitly nulled
    out causing immediate crash when using any PVR addon manipulating PVR
    recordings.

Subject: [PATCH 15/19] Avoid time_t in tm conversions

This should leave the possibility of time_t truncation on 32-bit
architectures only in GetAsTime(), what we can do nothing with.

Subject: [PATCH 17/19] XBDateTime: Use timezone info specified via timezone
 picker.

Fixes broken timezone picker as reported in Debian Bug#1011294.

Also fixes TZ-related issue spotted on reproducibility build
where TZ envvar specifying timezone as absolute pathname on Linux
and FreeBSD screwed date lib up.
