DESCRIPTION¶

These functions create and manipulate the time fields in an archive_entry. Supported time fields are atime (access time), birthtime (creation time), ctime (last time an inode property was changed) and mtime (modification time).

libarchive(3) provides a high-resolution interface. The timestamps are truncated automatically depending on the archive format (for archiving) or the filesystem capabilities (for restoring).

All timestamp fields are optional. The XXX_unset() functions can be used to mark the corresponding field as missing. The current state can be queried using XXX_is_set(). Unset time fields have a second and nanosecond field of 0.
