source: functions.c @ 4ebbfbc

release-1.9
Last change on this file since 4ebbfbc was 4ebbfbc, checked in by Jason Gross <jgross@mit.edu>, 10 years ago
Show the time zone in :info; replace ctime with strftime This fixes trac-#146. The new function owl_util_time_to_timestr takes a const struct tm * instead of a const time_t because, although we pass around time_t for just about everything else, this lets the caller decide whether to use localtime or gmtime (UTC). Note: I'm not sure that "%c" (which is locale-dependent) will always include the time zone. If not, or if we want a bit more consistency, we can switch to something like "%a %b %d %H:%M:%S %Y %Z" (like "Fri Jul 22 15:39:45 2011 EDT") or "%a %b %d, %Y %h:%M:%S %p %Z" (like "Fri Jul 22, 2011 03:39:45 PM 2011 EDT") or something. On linerva, "%c" seems to be equivalent to "%a %d %b %Y %h:%M:%S %p %Z" (like "Fri 22 Jul 2011 03:39:45 PM EDT").
