X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;ds=sidebyside;h=686553dfce92eb35b3709f64b687c2757334df86;hp=60960a260f7b5c695fd0717311d72ce62dd4eb43;p=rust.git

ci: add a check for clock drift

Recently we encountered multiple spurious failures where the crates.io
certificate was reported as expired, even though it's currently due to
expire in a few months. This adds some code to our CI to check for clock
drifts, to possibly find the cause or rule out a bad VM clock.
