Data File Time Shift
| Units: | h |
| Default Value: | 0 |
| Validation Rule: | Any Value |
| Description: | Number of hours to shift data in time when interpreting dates where a positive value means the data are from a time zone that is behind the 'reference' time zone. |
| Detail: |
Data File Time Shift is the number of hours to shift data in time when interpreting dates where a positive value means the data are from a time zone that is behind the 'reference' time zone.
Example
The following file contains data for three Region objects' Load:

If in fact these regions have different time zones the data should be shifted in time so that the simulation, which is formulated on a notional 'reference time zone', models the timing of the loads correctly. Assume that "Southeast" is our reference time zone, and that "North" is one hour behind and "Southwest is three hours behind.
To achieve this we can create three Data File objects and define their Time Shift properties as follows:
| Data File | Property | Value | Units | Filename |
|---|---|---|---|---|
| North | Filename | 0 | - | Load.csv |
| Southeast | Filename | 0 | - | Load.csv |
| Southwest | Filename | 0 | - | Load.csv |
| North | Time Shift | 1 | hrs | |
| Southeast | Time Shift | 0 | hrs | |
| Southwest | Time Shift | 3 | hrs |
The simulation results report in the 'reference time zone' thus:
