Last change on this file since 4f70ebc was 4f70ebc, checked in by Olly Betts <olly@…>, 10 years ago
src/: Add new "datestamp_numeric" field to struct img giving the datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we failed to convert it). For .3d >= v8, this field is reliable. We attempt to convert date strings in .3d <= v7 and CMAP XYZ files, but may get the timezone wrong.
Property mode set to `100644`
