Paragraph three of the DESCRIPTION section says that when TZ is set, but empty, then UTC is used. Later it says if the TZ filespec is omitted then the file /usr/share/zoneinfo/localtime is used. This is incorrect, it will use UTC in that case as well. Steps to reproduce: cd /usr/share/zoneinfo/ cp Antarctica/South_Pole localtime cd date Sun Jan 18 10:59:50 EST 2015 TZ=:Hongkong date Sun Jan 18 23:59:56 HKT 2015 TZ=:/usr/share/zoneinfo/localtime date Mon Jan 19 05:00:03 NZDT 2015 TZ=: date Sun Jan 18 16:00:11 UTC 2015 TZ=":" date Sun Jan 18 16:00:18 UTC 2015 TZ=':' date Sun Jan 18 16:00:24 UTC 2015 TZ=:/ date Sun Jan 18 16:00:34 2015 TZ=":/" date Sun Jan 18 16:00:40 2015 TZ="" date Sun Jan 18 16:00:45 UTC 2015 Signed-off-by: J William Piggott <elseifthen@xxxxxxx> --- The following changes since commit b58839b96d626e67da233d4bf7ba04d5dfcd0e66: syscalls.2: Remove some details for sync_file_range2() (2015-01-18 19:56:05 +0100) are available in the git repository at: git@xxxxxxxxxx:jwpi/man-pages.git tzset for you to fetch changes up to 2b0725c0b6f6788628567ea4d5cfc396898584a0: tzset.3: TZ filespec omitts the colon (2015-01-18 14:40:21 -0500) man3/tzset.3 | 10 ++-------- 1 file changed, 2 insertions(+), 8 deletions(-) diff --git a/man3/tzset.3 b/man3/tzset.3 index c1c98e1..36d2fd7 100644 --- a/man3/tzset.3 +++ b/man3/tzset.3 @@ -170,14 +170,8 @@ from a file: :[filespec] .RE .sp -If the file specification \fIfilespec\fP is omitted, the timezone -information is read from the file -.I localtime -in the system timezone directory, which nowadays usually is -.IR /usr/share/zoneinfo . -This file is in -.BR tzfile (5) -format. +If the file specification \fIfilespec\fP is omitted, or its value cannot +be interpreted, then Coordinated Universal Time (UTC) is used.
