1. The Challenge: A Country Is Not Always a Time Zone
Many Salesforce administrators assume that a customer’s country is sufficient to determine their local time.
In some cases, this is true.
For example:
- Germany uses a single time zone.
- Denmark uses a single time zone.
- Portugal uses a single mainland time zone.
However, many countries have multiple time zones.
Examples include:
- United States
- Canada
- Australia
- Brazil
- Mexico
- Russia
In these countries, knowing the country alone is often not enough to determine the correct local time.
This can create issues such as:
- Calling prospects too early
- Missing customers during business hours
- Sending automated emails at inappropriate times
- Incorrect reporting and scheduling
- Time-zone-aware automations making incorrect decisions
To provide accurate local time information, Salesforce organizations need a more precise approach.
2. Why Country Alone Is Often Not Enough
Consider the following Lead record:
Country: United States
Which time zone should Salesforce use?
Possible answers include:
- Eastern Time
- Central Time
- Mountain Time
- Pacific Time
- Alaska Time
- Hawaii-Aleutian Time
Without additional information, the system cannot know which one is correct.
A similar problem exists in countries such as Canada and Australia where customers may live thousands of miles apart while sharing the same country value.
As a result, relying solely on the country field can lead to inaccurate time calculations.
3. A Real-World Example
Imagine two Leads.
Lead A
Country: USA State: New York
Lead B
Country: USA State: California
Although both Leads are located in the United States, there is a three-hour difference between them.
If a sales representative starts calling prospects at:
9:00 AM Eastern Time
it may only be:
6:00 AM Pacific Time
for the California prospect.
Without accurate time-zone identification, organizations risk contacting customers outside normal business hours.
4. The Additional Challenge: States with Multiple Time Zones
The problem becomes even more complex in certain regions.
Some states and provinces span multiple time zones.
Examples include:
- Texas
- Florida
- Kansas
- Nebraska
- Oregon
In these situations, even the state value may not be sufficient.
For example:
Country: USA State: Florida
Florida contains areas that observe different time zones.
To identify the correct time zone, additional information may be required.
5. Why Postal Codes Can Improve Accuracy
One way to improve accuracy is to include postal code information.
Consider two records:
Record 1
Country: USA State: Florida Postal Code: Blank
Record 2
Country: USA State: Florida Postal Code: Defined
The second record provides more precise location information, allowing the correct time zone to be identified more reliably.
This becomes especially useful when working with regions that cross time-zone boundaries.
The more complete the address information, the more accurate the resulting local-time calculation.
6. How the Local Time App Handles Multiple Time Zones
The Local Time app uses a layered approach when determining a record’s time zone.
Step 1
Use the record’s address fields.
For countries with multiple time zones, both country and state information may be required.
Step 2
If address information is unavailable or incomplete, use the phone number to determine the location.
Step 3
If a country contains multiple time zones and the state value is missing, administrators can configure default time-zone settings.
Step 4
If no reliable location information is available, the application displays:
Unknown
This approach helps maximize accuracy while still handling incomplete customer records.
7. Best Practices for Salesforce Administrators
To achieve the most accurate local-time calculations, consider the following recommendations.
Capture Country and State Information
Whenever possible, require:
Country State/Province
especially for countries that span multiple time zones.
Collect Postal Codes
Postal codes can provide additional precision in regions where states or provinces include multiple time zones.
Standardize Address Data
Ensure users enter location information consistently.
Accurate data produces more reliable time-zone calculations.
Review Incomplete Records
Records with missing location information are more likely to produce inaccurate or unknown results.
Periodic data quality reviews can help resolve these issues.
8. Why Accurate Time Zones Matter
A difference of one or two hours may seem minor.
However, for sales, support, and marketing teams, timing can greatly influence outcomes.
Accurate time-zone information helps organizations:
- Call customers during business hours
- Schedule meetings more effectively
- Improve automation timing
- Route work appropriately
- Deliver a better customer experience
The larger and more global an organization becomes, the more important accurate time-zone data becomes.
9. Try the Local Time App
Determining a customer’s local time is easy when every country has a single time zone.
The real challenge occurs when multiple time zones exist within the same country.
The Local Time app helps Salesforce organizations accurately determine local time by using address information, phone numbers, UTC offsets, time-zone data, postal codes, and Daylight Saving Time adjustments.
This enables sales, support, marketing, and operations teams to make better decisions based on a customer’s actual local time.
