Usage
By using  good   time to indicate whether the period is ambiguous or unclear and can be made clearer by using more accurate language.

After doing so, it is a good idea to create a new When heading on that page's talk page, so as to provide a forum to discuss the unclear time reference.

For example
The following are some examples of unclear time references.

The seasons are used as time
Seasons are local phenomena and their usage as a substitute for dates, month names and the like is an example of systemic bias.

This usage often manifests itself in phrasing like the following:
 * (some event happened) in the (season) of (year).
 * (something was completed) by [the] (season) [of (year)].

Most commonly, such phrasing uses Northern Hemisphere temperate zone seasons interchangeably with month names or other times, and this can be the source of confusion for people in the tropics or in the opposite hemisphere.

Google can be used to find some examples of such references efficiently, and this suggests that a bot can be written to work in a similar manner. A Google search like  typically returns several thousand hits, of which maybe half are phrases like "the spring of [year]". This suggests that tens of thousands of pages in may be in need of attention to remove this ambiguous phrasing.

Other ambiguous time values
Other time references may also be vague or ambiguous. Wordings like "Recent" or other similar vague wordings may need clarification. Is "recent" used to mean last week, last month, last year, last century? Such wording may not be obvious to the reader unless it is clarified or reworded.
