.. leading zeros are required for `frontmatter` to treat them as dates
rather than strings, apparently per the YAML specification.
This was done by script:
```py
import re
import datetime
import pathlib
import sys
import frontmatter
rx = re.compile(r'^(\s*)date_added:.*$', re.M)
for path_str in sys.argv[1:]:
print(path_str)
path = pathlib.Path(path_str)
post = frontmatter.load(path)
date_added = post.get("date_added", "")
if isinstance(date_added, datetime.date):
continue
if isinstance(date_added, str):
try:
date_added = datetime.datetime.strptime(date_added, "%Y-%m-%d")
except ValueError as exc:
print(f"Failed to parse date {date_added} in {path_str}: {exc}")
continue
date_added = date_added.date()
content = path.read_text("utf-8")
new_content = rx.sub(lambda m: f"{m.group(1)}date_added: {date_added}", content)
assert content != new_content
path.write_text(new_content, "utf-8")
```

M5Stack's Timer Camera X is an all-in-one camera module based on ESP32, integrated with ESP32 chip and has 8M PSRAM. Why so much PSRAM? Well, the camera can shoot up to 2048x1536 resolution photos(!). The module also comes with a built-in 140mAh battery and LED status indicator. There is a reset button under the LED.
You can use the built-in RTC (BM8563) to keep track of time to create custom, specific sleep and wake-up schedules. In deep sleep, the standby current of the entire Camera X can be as low as 10 μA. This camera supports sending images through WiFi and via the USB serial debug port. The bottom HY2.0-4P I2C port output can be connected to other I2C peripherals such as Grove or Stemma QT devices when this cable is in use.
A friendly heads-up: The low-power power management used by the Timer Camera series is different from the CORE and StickC devices. When in use, the PWR button is used as a power-on button (long press 2 seconds). If you need to shut down the device, use the software API or press the Reset button on the PCB.
