Stardates

[Lawrence D'Oliveiro]

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

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.
