-Add support for use of the system timezone database, rather
-than embedding a copy.  Discussed upstream but was not desired.
-
-History:
-r20: adapt for timelib 2020.03 (in 8.0.10RC1)
-r19: adapt for timelib 2020.02 (in 8.0.0beta2)
-r18: adapt for autotool change in 7.3.3RC1
-r17: adapt for timelib 2018.01 (in 7.3.2RC1)
-r16: adapt for timelib 2017.06 (in 7.2.3RC1)
-r15: adapt for timelib 2017.05beta7 (in 7.2.0RC1)
-r14: improve check for valid tz file
-r13: adapt for upstream changes to use PHP allocator
-r12: adapt for upstream changes for new zic
-r11: use canonical names to avoid more case sensitivity issues
-     round lat/long from zone.tab towards zero per builtin db
-r10: make timezone case insensitive
-r9: fix another compile error without --with-system-tzdata configured (Michael Heimpold)
-r8: fix compile error without --with-system-tzdata configured
-r7: improve check for valid timezone id to exclude directories
-r6: fix fd leak in r5, fix country code/BC flag use in
-    timezone_identifiers_list() using system db,
-    fix use of PECL timezonedb to override system db,
-r5: reverts addition of "System/Localtime" fake tzname.
-    updated for 5.3.0, parses zone.tab to pick up mapping between
-    timezone name, country code and long/lat coords
-r4: added "System/Localtime" tzname which uses /etc/localtime
-r3: fix a crash if /usr/share/zoneinfo doesn't exist (Raphael Geissert)
-r2: add filesystem trawl to set up name alias index
-r1: initial revision

+
+Add support for use of the system timezone database, rather
+than embedding a copy.  Discussed upstream but was not desired.
+
+History:
+r21: retrieve tzdata version from /usr/share/zoneinfo/tzdata.zi
+r20: adapt for timelib 2020.03 (in 8.0.10RC1)
+r19: adapt for timelib 2020.02 (in 8.0.0beta2)
+r18: adapt for autotool change in 7.3.3RC1
+r17: adapt for timelib 2018.01 (in 7.3.2RC1)
+r16: adapt for timelib 2017.06 (in 7.2.3RC1)
+r15: adapt for timelib 2017.05beta7 (in 7.2.0RC1)
+r14: improve check for valid tz file
+r13: adapt for upstream changes to use PHP allocator
+r12: adapt for upstream changes for new zic
+r11: use canonical names to avoid more case sensitivity issues
+     round lat/long from zone.tab towards zero per builtin db
+r10: make timezone case insensitive
+r9: fix another compile error without --with-system-tzdata configured (Michael Heimpold)
+r8: fix compile error without --with-system-tzdata configured
+r7: improve check for valid timezone id to exclude directories
+r6: fix fd leak in r5, fix country code/BC flag use in
+    timezone_identifiers_list() using system db,
+    fix use of PECL timezonedb to override system db,
+r5: reverts addition of "System/Localtime" fake tzname.
+    updated for 5.3.0, parses zone.tab to pick up mapping between
+    timezone name, country code and long/lat coords
+r4: added "System/Localtime" tzname which uses /etc/localtime
+r3: fix a crash if /usr/share/zoneinfo doesn't exist (Raphael Geissert)
+r2: add filesystem trawl to set up name alias index
+r1: initial revision
