Created attachment 543242 [details] xfce4-datetime-plugin-0.7.0-x32-fix-GTimeVal-time_t-conversion.patch When converting values from a GTimeVal struct to time_t the plugin uses a pointer-cast assuming that time_t has the same size as long. This assumption does not hold for this ABI with glibc where time_t is still a 64-bit value but long has only 32 bit (default/linux/amd64/17.0/x32 profile). As a result the conversion pulls in the microseconds field from GTimeVal giving quasi-random date and time values.
