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.
Perl - turning seconds into days, hours, minutes and seconds

So often you'll be working within a program in seconds - elapsed times, delays, that sort of thing - but want to report times back to the user in terms of hours, minutes and seconds. The conventional programming way to do this is to do a series of divisions and grab the remainder, but in Perl you can use the gmtime function which converts a number of seconds from 1st January 1970 into a list of 9 elements of a date. Up to 365 days, you can simply take the days-into-year and hours, minutes and seconds value returned by gmtime.

# Convert seconds to days, hours, minutes, seconds
$seconds = 94054;
@parts = gmtime($seconds);
printf ("%4d %4d %4d %4d\n",@parts[7,2,1,0]);


When I run that:

earth-wind-and-fire:~/jun06 grahamellis$ perl ts
   1   2   7  34
earth-wind-and-fire:~/jun06 grahamellis$


A conversion of 94.054 seconds into 1 day, 2 hours, 7 minutes and 34 seconds.
