<p style="color: grey"> Python recipe 578817 by <a href="/recipes/users/4189027/">Peter Santoro</a> (<a href="/recipes/tags/age/">age</a>, <a href="/recipes/tags/lru_cache/">lru_cache</a>). </p> <p>Return a timestamp string for @lru_cache decorated functions.</p> <p>The returned timestamp is used as the value of an extra parameter to @lru_cache decorated functions, allowing for more control over how often cache entries are refreshed. The lru_timestamp function should be called with the same refresh_interval value for a given @lru_cache decorated function. The returned timestamp is for the benefit of the @lru_cache decorator and is normally not used by the decorated function.</p> <p>Positional arguments: refresh_interval -- in minutes (default 60), values less than 1 are coerced to 1, values more than 1440 are coerced to 1440</p>
