For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Question about 'clock format' command

Posted by Dimon (Dimon), 22 February 2006
A short simple console snapshot:

set starttime [clock seconds]

set endtime [clock seconds]

set aTime [expr $endtime - $starttime]

clock format $aTime -format %T

The question is next: I recieved 52 seconds but after convertion it into format: %T (HH:MM:SS), I saw 2 hours and 52 seconds. Hm... Where is the error and how can I fix it?

Clock format gives you a time from midnight, GMT, 1st January 1970. So if you subtract 2 times and try to use it to format that time, it will ONLY work if the computer is in a GMT timezone.

To solve your problem, move to England

Oh, Graham, greate thanks for your invitation  
But I have solve that problem after I found a -gmt key of clock command. The string:
clock format $aTime -format %T -gmt 1

formats a time according to my computer's clock
