Usage

If you have a modern client which supports server-time capability, timestamps are automatically shown correctly. Otherwise, one of scripts below might help. But in that case consider upgrading your client instead.

Instructions for ancient clients

If you want real timestamps you should use these settings for your user: 

TimestampFormat = [%H:%M:%S]
AppendTimestamp = false
PrependTimestamp = true

It currently supports Channel, Query, Wallops, Notice and Servernotices

Format

strftime arguments can be used for the timestamps, more details and arguments can be found at opengroup.org[1]. 

 %a - the locale's abbreviated weekday name. 
 %A - the locale's full weekday name. 
 %b - the locale's abbreviated month name. 
 %B - the locale's full month name. 
 %c - the locale's appropriate date and time representation. 
 %C - the century number (the year divided by 100 and truncated to an integer) as a decimal number [00-99]. 
 %d - the day of the month as a decimal number [01,31]. 
 %D - same as %m/%d/%y. 
 %e - the day of the month as a decimal number [1,31]; a single digit is preceded by a space. 
 %f - sub-second, e.g. %3f is number of milliseconds (the default), and %6f is number of microseconds. (since ZNC 1.7.0)
 %h - same as %b. 
 %H - the hour (24-hour clock) as a decimal number [00,23]. 
 %I - the hour (12-hour clock) as a decimal number [01,12]. 
 %j - the day of the year as a decimal number [001,366]. 
 %m - the month as a decimal number [01,12]. 
 %M - the minute as a decimal number [00,59]. 
 %n - a newline character. 
 %p - the locale's equivalent of either a.m. or p.m. 
 %r - the time in a.m. and p.m. notation; in the POSIX locale this is equivalent to %I:%M:%S %p. 
 %R - the time in 24 hour notation (%H:%M). 
 %S - the second as a decimal number [00,61]. 
 %t - a tab character. 
 %T - the time (%H:%M:%S). 
 %u - the weekday as a decimal number [1,7], with 1 representing Monday. 
 %U - the week number of the year (Sunday as the first day of the week) as a decimal number [00,53]. 
 %V - the week number of the year (Monday as the first day of the week) as a decimal number [01,53]. If the week containing 1 January has four or more
      days in the new year, then it is considered week 1. Otherwise, it is the last week of the previous year, and the next week is week 1. 
 %w - the weekday as a decimal number [0,6], with 0 representing Sunday. 
 %W - the week number of the year (Monday as the first day of the week) as a decimal number [00,53]. All days in a new year preceding the first Monday
      are considered to be in week 0. 
 %x - the locale's appropriate date representation. 
 %X - the locale's appropriate time representation. 
 %y - the year without century as a decimal number [00,99]. 
 %Y - the year with century as a decimal number. 
 %Z - the timezone name or abbreviation, or by no bytes if no timezone information exists. 
 %% - %.

mIRC

Notice: mIRC supports server-time since 7.33, no special script needed.

Instructions for ancient mIRC

This script requires these settings for your user: 

TimestampFormat = [%H:%M:%S]
AppendTimestamp = false
PrependTimestamp = true

Otherwise you have to adjust the regex pattern in the script that grabs the timestamp.

It handles

  • Channel messages
  • Savebuff output
  • Channel notices
  • Channel actions

Configuration (optional)

If lines are too long to fit the window width they are wrapped so that the wrapped lines will line up after the nick. To disable that behavior, set %INDENT_LINES to $false.

Nicks will be prefixed with their mode identifier (so "nick" becomes "@nick" for example). To disable this behavior, set %PREFIX_NICKS to $false.

The beginning and end of buffer playback are marked with the default line separator by default. This can be changed to NORMAL to display the usual *** Buffer Playback. and *** Playback Complete messages or to NONE to not show any status message at all.

If you run into problems like all messages being displayed twice because of other ON TEXT processing scripts, try to set %EXTERNAL_RENDERER to $false.

The script also allows the use of spaces.dll to preserve consecutive spaces. To enable it just put spaces.dll (http://www.xise.nl/mirc/) into your Application Data folder and set %USE_SPACES_DLL to $true.

Script

Information about loading mIRC scripts can be found here.

irssi

Notice: irssi supports server-time since 1.3, just set /set show_server_time on. For details refer to the settings documentation.

Go to https://scripts.irssi.org and install the server_time.pl script. Note that you must connect to ZNC while the script is already loaded in order for it to work (loading it after you've connected will do nothing).

WeeChat

Notice: WeeChat supports server-time since 0.4.0, no special script needed.

But if you don't want to upgrade, you can try znc-playback.py

Other clients

Check documentation for your client, maybe it supports server-time too.

Clients which don't support server-time will just show the playback like this: 

[08:44:30] Goldfish [monkey@2001:db8:a22c:67f::1] joined #unicorns
[08:44:30] Channel topic: O_o
[08:44:30] Topic set by Romeo!~opossum@2001:db8:451:eea6:5574:af2e:46:fe61 on Mon Mar 24 19:31:45 2014
[08:44:30] <***> Buffer Playback...
[08:44:30] <Rusty> [24 Jan 2015, 11:09:00] ah, the subfolder
[08:44:30] <Rusty> [24 Jan 2015, 11:09:00] meh
[08:44:30] <jor> [24 Jan 2015, 11:10:07] still not found
[08:44:30] <***> Playback Complete.

In this example the following settings are used: 

AppendTimestamp = false
PrependTimestamp = true
TimestampFormat = [%d %b %Y, %H:%M:%S]

It feels less integrated with client, but it's not very harmful.
