Jean-François Milants b4ff1f9ca2 Simple Weather Service : Fix timestamp
In the documentation, specify that the timestamp is expressed in seconds from epoch (instead of nanoseconds).
SimpleWeatherService now uses "localtime" (GetCurrentDateTime()) instead of UTC time.

# Simple Weather Service
## Introduction
The Simple Weather Service provides a simple and straightforward API to specify the current weather and the forecast for the next 5 days.
It effectively replaces the original Weather Service (from InfiniTime 1.8) since InfiniTime 1.14.
## Service
The service UUID is `00050000-78fc-48fe-8e23-433b3a1942d0`.
## Characteristics
## Weather data (UUID 00050001-78fc-48fe-8e23-433b3a1942d0)
The host uses this characteristic to update the current weather information and the forecast for the next 5 days.
This characteristics accepts a byte array with the following 2-Bytes header:
- [0] Message Type :
- `0` : Current weather
- `1` : Forecast
- [1] Message Version : Version `0` is currently supported. Other versions might be added in future releases
### Current Weather
The byte array must contain the following data:
- [0] : Message type = `0`
- [1] : Message version = `0`
- [2][3][4][5][6][7][8][9] : Timestamp (64 bits UNIX timestamp, number of seconds elapsed since 1 JAN 1970)
- [10, 11] : Current temperature (°C * 100)
- [12, 13] : Minimum temperature (°C * 100)
- [14, 15] : Maximum temperature (°C * 100)
- [16]..[47] : location (string, unused characters should be set to `0`)
- [48] : icon ID
- 0 = Sun, clear sky
- 1 = Few clouds
- 2 = Clouds
- 3 = Heavy clouds
- 4 = Clouds & rain
- 5 = Rain
- 6 = Thunderstorm
- 7 = Snow
- 8 = Mist, smog
### Forecast
The byte array must contain the following data:
- [0] : Message type = `1`
- [1] : Message version = `0`
- [2][3][4][5][6][7][8][9] : Timestamp (64 bits UNIX timestamp, number of seconds elapsed since 1 JAN 1970)
- [10] Number of days (Max 5, fields for unused days should be set to `0`)
- [11,12] Day 0 Minimum temperature (°C * 100)
- [13,14] Day 0 Maximum temperature (°C * 100)
- [15] Day 0 Icon ID
- [16,17] Day 1 Minimum temperature (°C * 100)
- [18,19] Day 1 Maximum temperature (°C * 100)
- [20] Day 1 Icon ID
- [21,22] Day 2 Minimum temperature (°C * 100)
- [23,24] Day 2 Maximum temperature (°C * 100)
- [25] Day 2 Icon ID
- [26,27] Day 3 Minimum temperature (°C * 100)
- [28,29] Day 3 Maximum temperature (°C * 100)
- [30] Day 3 Icon ID
- [31,32] Day 4 Minimum temperature (°C * 100)
- [33,34] Day 4 Maximum temperature (°C * 100)
- [35] Day 4 Icon ID
