The exact issuance and expiry times in the device rows' hover titles were rendered in UTC, which reads as wrong to anyone not living there. - Mark the dates with a <time> element carrying the absolute (UTC) timestamp, rather than a custom data attribute whose name claimed to hold local time - Rewrite those titles in the browser's own zone, keeping the server's UTC rendering as the fallback for when JavaScript is unavailable - Only convert values that carry an explicit offset, so a date-only <time> is not read as UTC midnight and shifted onto the previous day - Give the revoke button a little more room from the device name and dates Part of #254
