Subject: [pbs-devel] [PATCH pxar/backup 0/6] bump timestamps to 96 bit
Date: Tue, 28 Jul 2020 12:33:14 +0200 [thread overview]
Message-ID: <20200728103321.16843-1-w.bumiller@proxmox.com> (raw)
So apparently modification time values of *before* Jan 1 1970 are a
thing, so here's support for that...
This bumps the `Entry` struct in pxar (meaning an API bump), and still
supports reading old archives.
Note that I've introduced a new `StatxTimestamp` struct. I chose this
name as the `statx(2)` manpage's `struct statx_timestamp` is the only
struct which actually documents the fact that only the seconds are
signed, and the nanoseconds are *positive* and *relative* to the
seconds, iow. a timestamp of "-3.5 seconds" is represented as "-4
seconds, plus 500_000_000 nanoseconds". (The only other time I found
this to be explicitly mentioned is in the `chrono` crate's
`TimeZone::timestamp` method which explicitly creates a "DateTime from
the number of non-leap seconds since (...) 1970 (...) and the number of
nanoseconds since the last whole non-leap second.".
