Answer 1: Changing PmWiki's time output format
1: PmWiki
PmWiki uses the $TimeFmt variable and PHP's strftime function to format its dates and times. The default setting of $TimeFmt is "%B %d, %Y, at %I:%M %p", which displays the name of the month (d), year (I), minutes (%M), and am/pm setting (%p).
The documentation for strftime describes the various %-parameters that are available.
PmWiki$TimefmtPHPstrftime
$TimeFmt "%B %d, %Y, at %I:%M %p"
(d)(I)(%M)/(%p)
strftime%
Thus, to change the display of dates and times to a "mm-dd-yyyy hh:mm" format, set $TimeFmt in local/config.php as
"mm-dd-yyyy hh:mm"
local/config.php$TimeFmt
$TimeFmt='%m-%d-%Y %H:%M'; # mm-dd-yy hh:mm$TimeFmt="%d.%m.%G, at %R %Z"; # german (ISO year) format
Answer 2: Setting the time zone
To change your timezone, you generally need to know the value of the "TZ" or "timezone" environment variable. These are defined for different localities around the world. For example, in the U.S. the Eastern time zone setting is generally "EST5EDT", which gives the name of the timezone ("EST"), the number of hours offset from GMT (5), and a string to be used if the zone honors daylight savings time ("EDT").
Thus, to change PmWiki's timezone to be U.S. Eastern Time, add the following line to local/config.php.
putenv("TZ=EST5EDT");
Some common timezone values (feel free to add to this list):
EST5EDT U.S. Eastern Standard/Daylight Time
CST6CDT U.S. Central Standard/Daylight Time
MST7MDT U.S. Mountain Standard/Daylight Time
MST7 U.S. Mountain Standard Time (Arizona)
PST8PDT U.S. Pacific Standard/Daylight Time
AKST9AKDT U.S. Alaska Standard/Daylight Time
UTC0 Universal Coordinated Time
GMT0 Greenwich Mean Time
CET-1CEST Central Europe Time/Central Europe Summer Time
NZS-12NZD New Zealand Standard/Daylight Time
