munge H:M:S and M:S into seconds for zsh time command with ruby regexes

gistfile1.txt

For example for data looking like

qwerasdvzxcasdf  0.62s user 18.55s system 92% cpu 20.678 total
asdfasdf 838.56s user 10.75s system 100% cpu 14:08.98 total
acvzxcvzxcv 3:15:12.2 total
asdfadsf 0.22s user 6.24s system 0% cpu 16:01.30 total

output those 4 numbers in seconds

20.678
848.98
11712.2
961.3

COMMAND:
ruby -ne 'puts $_[/(\S+) total/,1].sub(/^(\d+):(\d+):(\S+)/){ ($1.to_i*3600 + $2.to_i*60 + $3.to_f).to_s }.sub(/^(\d+):(\S+)/){ ($1.to_i*60 + $2.to_f).to_s }'

ruby code expanded to multiple lines.  First it tries to match the H:M:S format, then the M:S format.

    s = "12:10:4.1"
    puts s.sub(/^(\d+):(\d+):(\S+)/){ 
      ($1.to_i*3600 + $2.to_i*60 + $3.to_f).to_s 
    }.sub(/^(\d+):(\S+)/){
      ($1.to_i*60 + $2.to_f).to_s
    }
