I tried both previously but the bash shell still converts the number. If the leading zero is removed then it is treated as integer. Again, only the version of bash I use is doing it.

%06s is obviously not portable.
On different OS I get different results:
Code:
printf "%06s\n" 01140
 01140

Code:
printf "%06s\n" 01140
001140

However, never this is seen as a number.

Here is another one for bash:
Code:
x=01140
x=00$x; echo "${x: -6:2} hours, ${x: -4:2} minutes,  ${x: -2} seconds"

The following seems to be pretty portable:
Code:
printf "%06.f\n" 01140
001140

Code:
printf "%06g\n" "$x"
001140
