When there is a significant difference between the user's browser's time
and the system time, a button appears in the web UI to fix the system
time. This time will then be used to correct both data inside of PCAPs
and any metadata.
We don't actually set the system time to this value. Instead, rayhunter
adjusts any timestamps it handles by an offset. That offset defaults to
zero, and the user adjusts it by hitting the button in the web UI. The
main reason for this is device portability.
I haven't investigated whether it would actually be easy to set the real
system time. It's possible that it works the same way across all
devices.
...and make a small UI change so that folks won't get concerned about parsing errors.
Right now all the "undecoded extensions" noise goes into
rayhunter-daemon.log, and users get concerned about it when browsing
that through the UI.
Mixing async and sync I/O leads to a multitude of complications, and
generally speaking it's much more convenient to stick to one paradigm
or the other. Since axum (and many other HTTP servers) use async,
and since async is a convenient model for performing operations like
"handle an MPSC message or file read, whichever happens first", let's
commit to an async interface.
