return difference between two date/time strings <t1>, and <t2>, in days to <precision> decimal places. Converts
each date/time string to a unix timestamp (seconds), subtracts <t1> from <t2>, divides the difference by the number
of seconds in a day (86400) and returns a formatted string to <precision> decimal places. The default precision
is 3 decimal places. A positive result is returned when <t2> is the same as, or is 'later' (more recent) than,
<t1>; negative results else.

to call this from a template:
{{#invoke:diff days|diff_days|<t1>|<t2>|precision=}}
where <t1> and <t2> are date/time strings acceptable to the MediaWiki #time parser
