# time
This library _extends_ the built-in [MicroPython `time`
module](https://docs.micropython.org/en/latest/library/time.html#module-time) to
include
[`time.strftime()`](https://docs.python.org/3/library/datetime.html#strftime-and-strptime-behavior).
`strftime()` is omitted from the built-in `time` module to conserve space.
## Installation
Use `mip` via `mpremote`:
```bash
> mpremote mip install time
```
See [Package management](https://docs.micropython.org/en/latest/reference/packages.html) for more details on using `mip` and `mpremote`.
## Common uses
`strftime()` is used when using a loggging [Formatter
Object](https://docs.python.org/3/library/logging.html#formatter-objects) that
employs
[`asctime`](https://docs.python.org/3/library/logging.html#formatter-objects).
For example:
```python
logging.Formatter('%(asctime)s | %(name)s | %(levelname)s - %(message)s')
```
The expected output might look like:
```text
Tue Feb 17 09:42:58 2009 | MAIN | INFO - test
```
But if this `time` extension library isn't installed, `asctime` will always be
`None`:
```text
None | MAIN | INFO - test
```
