`split` | character string to split if using token, default is a period.

### Details

If token is FALSE, then the station name and component are selected using substr, i.e. by column number.

### Value

DB with epoch time and station information appended,

`t1` | epoch start time

    hr=0, mi=0, sec=0, dur=0))
    #### interactively fix the DB list
