Usage instructions

This template prints the current UTC time offset by ($UsualDifferenceFromUTCForThisLocation + $DSTAdjustment) hours where the terms beginning with $ are named arguments to the template.

Rationale

The reason we separate out the "usual" difference from UTC and the DST adjustment is that the first part remains constant forever.

Whereas the second part changes twice a year. This arrangement is the best way to minimize the number of pages we have to change when the clock changes. For example we can write

The current time in London is {{CurrentTimeIn|UsualDifferenceFromUTCForThisLocation = 0 | DSTAdjustment = {{CurrentDaylightSavingsOffsets/Europe}}

and

The current time in Paris is {{CurrentTimeIn|UsualDifferenceFromUTCForThisLocation = 1 | DSTAdjustment = {{CurrentDaylightSavingsOffsets/Europe}}

and when the clocks change in Europe, the only page we have to change is {{CurrentDaylightSavingsOffsets/Europe}} which is minimal number of pages. This template is usually wrapped by another template which controls the positioning of the time on the page. One example is {{CurrentTimeInHeader}} which puts the time near the top of the page.
