release-1.9
Last change on this file since a4ae221 was 6646fdb, checked in by David Benjamin <davidben@mit.edu>, 10 years ago
Restore correct semantics of message 'time' attribute This rewrites part of 4ebbfbc5360fa004637dd101f5a0c833cdccd60a. We can't replace every instance of ctime with a user-formatted time, as the time attribute is not user-formatted. It is (unfortunately) the API for perl to override the timestamp and owl_perlconfig_hashref2message expects a particular format for strptime. We should not then flip the values around once they reach C. (Especially not a locale-dependent one.) Rename *_to_timestr functions to owl_util_format_* so it is clear the function should only be used for user-formatted times.
