## Install
From pip

`pip install temporal-cache`

Or from source

`python setup.py install`

## Why?
I needed something that would automagically refresh at 4:00pm when markets close.

```python3

    @expire(hour=16)
    def fetchFinancialData():

```

## Interval Cache
The interval cache expires every `time` interval since its first use

```python3

    @interval(seconds=5, minutes=2)
    def myfoo():
        '''myfoo's lru_cache will expire 2 minutes, 5 seconds after last use'''
```


## Expire Cache
The expire cache expires on the time given, in scheduler/cron style.

```python3

    @expire(second=5, minute=2)
    def myfoo():
        '''myfoo's lru_cache will expire on the second minute, fifth second of every hour, every day, etc'''
```


## Caveats
Python hashing symantics persist. Dicts will be frozen, lists will be converted to tuples. Users are advised to pre-freeze to avoid issues.
