.Sh DESCRIPTION
These functions create and manipulate the time fields in an
.Vt archive_entry .
Supported time fields are atime (access time), birthtime (creation time),
ctime (last time an inode property was changed) and mtime (modification time).
.Pp
.Xr 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).
.Pp
All timestamp fields are optional.
The
.Fn XXX_unset
functions can be used to mark the corresponding field as missing.
The current state can be queried using
.Fn XXX_is_set .
Unset time fields have a second and nanosecond field of 0.
