So: 19:09 is 19 minutes and 9 seconds ? It is not HHMMSS for that you should have _HHMMSS="00:19:09" I found a bug in my solution --- time zone problems, so setting to GMT is needed: _HHMMSS="19:09:00" seconds=$( TZ=GMT date --date="1 january 1970 $_HHMMSS" "+%s" ) echo seconds=$seconds seconds=68940 _HHMMSS="00:19:09" seconds=$( TZ=GMT date --date="1 january 1970 $_HHMMSS" "+%s" ) echo seconds=$seconds seconds=1149 > so, it seems date is also somehow parsing that value as octal even though it > is being formatted in a date friendly way. is there a way to exactly specify > the encoding of the input for date? -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.
