====Driver Date Timezones==== Most ARDI historical drivers will need to be given a timezone. If you have multiple different sources of information, it's important to know that you're looking at the same point in time. Unfortunately, some systems record their information in **local** time, while others record their data in **UTC**. Still others never get correctly updated for daylight savings time. By adjusting the driver timezone, you can ensure that the dates from your data source are interpreted correctly.
