The input data, when a certificate is not found, was an unpunctuated
numerical representation of date. eg: '220613123456'.
Format this input to: '22-06-13 12:34:56' for use.
Also, disambiguate between certificate-data verses database-data
by renaming the database variables from 'crt_foo' to 'db_foo'.
Also, disambiguate between full-date verses epoch-date-seconds
by renaming epoch-date-seconds variables from 'foo' to 'foo_s'.
Also, improvements to status reports output format.
Also, improve related comments.
Closes: #568
