Subject: config: provide UTC timestamp control

`DATE_UTC_OPTION` is set in `Prepare_config()` for use by scripts, even
though only a few scripts will actually use it, since it allows those
scripts to be cleaner. we may want to possibly extend this as a
`DATE_OPTIONS` variable perhaps as part of enabling proper reproduciblity.
