Feature Proposal: adjusting time according to refresh interval

Currently, `i3status` has a refresh interval and all widgets are updated according to this interval.

Assume, for the sake of argument, we use a `tztime` widget in the form `hh:mm`, showing hours and minutes of the current time and an interval time of 60s.
In this configuration, the clock is behind the actual time for a certain amount of time (varying from 1s to 59s, depending on how i3status' refresh coincides with the actual minute turnover).

For some people it is preferrable to have the `tztime` widget *advance* the clock instead of lagging behind.

This could be implemented in two ways:
1) introduce an optional bool-flag in tzdata and correct the time accordingly by the global `interval` value.
2) introduce an optional correction value to tzdata by which the clocktime can be adjusted.

Would either of these options be merged upstream?
