Package: wtmpdb
Version: 0.72.0-1
Severity: normal
Dear Maintainer,
for the command-line argument `last -p <TIME>` there are existing at
least 4 issues:
1. last -p now
Works on the older util-linux version and shows all current
"still ..." active sessions. But the wtmpdb version, which I am
reporting here outputs
$> last -p now
Invalid time value 'now'
2. last -p <TIME>
The <TIME> is neither interpreted as UTC nor as local time. My
current system is using time zone (+0100) plus summer time, which
results in (CEST, +0200).
$> timedatectl
Local time: Sat 2025-04-05 04:08:45 CEST
Universal time: Sat 2025-04-05 02:08:45 UTC
RTC time: Sat 2025-04-05 02:08:45
Time zone: Europe/Berlin (CEST, +0200)
System clock synchronized: yes
NTP service: active
RTC in local TZ: no
In the following example a su(1) session starts at 03:39 local
time. To request it using -p argument I need to substract 1h,
i.e. 02:39. Don't know why 1h.
$> wtmpdb last -p '2025-04-05 02:40:00'
root pts/0 Sat Apr 5 03:39 - 03:47 (00:07)
dirk tty7 :0 Sat Apr 5 01:48 - still logged in
reboot system boot 6.12.20-amd64 Sat Apr 5 01:27 - still running
wtmpdb begins Fri Apr 4 19:01:21 2025
$> wtmpdb last -p '2025-04-05 02:38:00'
dirk tty7 :0 Sat Apr 5 01:48 - still logged in
reboot system boot 6.12.20-amd64 Sat Apr 5 01:27 - still running
wtmpdb begins Fri Apr 4 19:01:21 2025
3. last -p <RFC 3339 TIME>
Wishlist: Would be nice if <TIME> accepts fully the RFC 3339
format. Then the following example should work, which is
equivalent to `last -p now`:
$> last -p "$(date --rfc-3339=seconds)"
Invalid time value '2025-04-05 04:26:47+02:00'
4. last -p
Wishlist: Would be nice to make the <TIME> optional, like
[<TIME>]. This should be equivalent to `last -p now`.
Greets,
Dirk =)
