From... you guessed! man time:

l: TIME -- CPU Time
Total CPU time the task has used since it started. When 'Cumulative
mode' is On, each process is listed with the cpu time that it and
its dead children has used. You toggle 'Cumulative mode' with 'S',
which is a command-line option and an interactive command. See the
'S' interactive command for additional information regarding this
mode.

so you process has used just over 25 and a half *minutes* of CPU time.
