System : OpenBSD 4.7
Details : OpenBSD 4.7-beta (GENERIC.MP) #399: Wed Jan 27 12:22:57
MST 2010
[email protected]:/usr/src/sys/arch/i386/compile/GENERIC.MP
Architecture: OpenBSD.i386
Machine : i386
>Description:
the time macros supported in PS1 (and PS2) (eg '\t', '\A', etc)
seem to use the timezone present when the shell was invoked, and
subsequently the shell seems to not notice if the timezone specified in
the environment (TZ) is changed.
tested on 4.7-beta / 20100127. i don't currently have access to
a more current -current.
>How-To-Repeat:
following example shows:
- current date; current value of TZ (which is set in this case)
- changing PS1 to use the PS1 time macros
- setting TZ in the environment and retrieving the date
- exporting TZ and retrieving the date (no change in effect - normal)
- unsetting TZ and retrieving the date (falling back to system setting)
- value of the system setting
- attempt to demonstrate that PS1 still contains the native macros and
not incorrect or stale string literals

# t:14:20:17 T: 2:20:17 @:02:20:17 PM A:14:20 D:PDT $ readlink /etc/localtime
/usr/share/zoneinfo/right/US/Eastern
# t:14:20:24 T: 2:20:24 @:02:20:24 PM A:14:20 D:PDT $ set | grep ^PS1
PS1='# t:\t T:\T @:\@ A:\A D:\D{%Z} $ '
# t:14:20:30 T: 2:20:30 @:02:20:30 PM A:14:20 D:PDT $
>Fix:
only other experience i have is bash(1), which appears to reflect
TZ changes after running an external command (subsequent to altering
value of TZ). internal commands do not appear to trigger an update
