I updated my proposed lru_timestamp function with the following changes:
1) restricted refresh_interval to int type
2) updated doc string
Updated doc string follows:
def lru_timestamp(refresh_interval=60):
""" Return a timestamp string for @lru_cache decorated functions.
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.
Positional arguments:
refresh_interval -- in minutes (default 60), values less than 1
are coerced to 1, values more than 1440 are
coerced to 1440
"""
