Subject: [PATCH 08/17] 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 10/17] 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 11/17] 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 c681095ef7c2e3bf0a71d4e3c8eb64f5f82a6e2d 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 12/17] 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 17/17] 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.
