  • Stardates

    From Lawrence D'Oliveiro@21:1/5 to All on Fri Feb 16 23:17:12 2024
    Here’s a command that produces date/time numbers reminiscent of “stardates”: days (and fractions of a day) since 00:00:00 1-Jan-1970 UTC, aka the Unix epoch.

    ldo@theon:~> bc <<<"scale = 1; $(date +%s) / 86400"
    19769.9

    At one point I was using this for version numbers for my Android apps.

    "No. of days since the Epoch" is also used in
    (some?) /etc/shadow files to indicate
    when a password expires, as well as
    when it was last set.

    Nifty. You could also do (this is more typing, but seems cleaner to me):

    $ gawk 'BEGIN { printf "%.1f\n",systime()/86400 }'

    Yeah, but those are integers. Adding a decimal point makes it a bit more,
    I don’t know ... stardatey.
