Dealing with UTC/DST chart issues and adjustments

On rare occasions, charts may display inaccuracies due to historical Daylight Saving Time (DST) variability, particularly in the United States prior to the Uniform Time Act of 1966. These inconsistencies in local DST observance can affect the UTC offsets applied to charts, leading to discrepancies. Here’s how to identify and resolve these issues.

Understanding the DST Issue

Before 1966, there was no federal mandate for DST observance in the United States, resulting in varying practices across states and even within local jurisdictions. For example:

• Some states did not observe DST at all until well after 1966.
• The start and end dates for DST varied significantly between locations.

This lack of standardization can cause discrepancies in charts for individuals born during this period, as the system may not apply the correct UTC offset for their birth location and time.

Identifying the Issue

If you believe your chart may be affected, look for the following signs:

• The chart does not match your known design (e.g., type, authority, profile, etc.).
• You were born in the U.S. between 1945 and 1966, during a period of inconsistent DST observance.
• The UTC offset appears incorrect compared to historical records for your location and time of birth.

Temporary Solution: Manual Adjustment

You can manually adjust your birth time to correct the issue by following these steps:

1. Determine whether the UTC offset should be adjusted. For example, if the chart is using UTC-5 but your location at the time of birth should have been UTC-6, you’ll need to shift the time by one hour.
2. Visit the onboarding process to re-enter your birth details.
3. In the time field, adjust the birth time forward or backward by one hour as needed.
4. Save the updated details and review the new chart to ensure it reflects the correct information.

Example Adjustment

If you were born at 3:00 PM in a location where the correct UTC offset was UTC-6, but the system applies UTC-5:

• Re-enter your birth time as 2:00 PM to adjust for the one-hour discrepancy.
• Generate the chart again and verify its accuracy.

When to Contact Support

If you’ve tried adjusting the time and the chart is still incorrect, or if your birth details are outside the 1945–1966 period, please contact our support team with the following information:

• Your full name.
• Your birth date, time, and location.
• A description of the issue you’re experiencing.
