Subtask 2: Estimate the offset of the values of "MOS" to UTC. Store them in a column called "OffsetUTC". (Data Manipulation)
Subtask 3: Order all sales according to a reconciled UTC-equivalent of the moment of sale and analyze the data. (Data Analysis)
Subtask 4: Obtain statistics and visualizations that will respond to the Main Task and further improve the analysis of your data. (Data Visualization)
