Data: Prepare for data with only day time hours and cut year by seasons

[FanWangEcon]

Alternative time considerations

Part 1, Construct day time hours only file

Building from the hourly file with all times, we construct the china-time specific day-time only hours file, we develope a script where we can specific the start hour and end hour of the day, and we develope a strategy to convert from UTC time information to China time informaiton

For more details see PIRE-CEC::issue-35.

Part 2, Construct non-winter time only

Building from the hourly file with all times, we construct the China-time specific non-winter hours only file, we follow the code from Part 1, with now month exclusion. Excluding Jan/Feb/Nov/Dec. See https://en.wikipedia.org/wiki/Climate_of_China#Examples.

Algorithm

1. Load libraries
2. Day time hour parameters, inclusive boundaries 6 to 22
3. Get paths, constructed in R-script/ffs_pirecec_support.R
4. Data file names
5. Read in file, all hours data
6. Pivot longer
7. Convert hours to utc time format
8. Convert UTC time to time in Shanghai
9. Cut non daytime hours
10. reindex hour of year
11. select and reshape to wide
12. save
