Time period tool allows creating new time periods applicable in best sellers and trending recommendations. By default, all top lists use one week as a time period for top lists. Under time periods menu you can control time periods adding new, removing old and editing existing.
Delete Time Period removes the period.
Add new time period adds a new one. Applicable time unit is one hour.
Note that creating a new time period scoring might take some time depending on how much traffic and products you have. The time period will be immediately available under the recommendation settings, but after creating a new time period slot it might take from few minutes to few hours before Nosto starts populating products.
