What is Time Zone Standardization?
Alvys uses time zone standardization to ensure consistent handling and display of fuel and toll transaction times across the platform. This means all transactions are stored in Coordinated Universal Time (UTC) and are displayed to users in their local time zone. The goal of this approach is to eliminate discrepancies caused by varying local times while maintaining a uniform standard for reporting.
Example of Time Conversion
A fuel transaction recorded by EFS:
Original timestamp (UTC): 2024-09-01 at 21:30 UTC
Displayed in EFS reports: 2024-09-01 at 15:30 UTC-6 (Central Time)
Displayed in Alvys:
East Coast (UTC-5): 2024-09-01 at 16:30
West Coast (UTC-7): 2024-09-01 at 14:30
Why Standardize Time Zones?
Using UTC as a standard for storing fuel transactions ensures consistency across integrations with various providers. Different providers handle time data differently—some use local time zones while others use UTC. By standardizing, Alvys simplifies integrations and reduces complexity. For instance, integrating with a provider like EFS, which stores transactions in CST but displays them to users in local time zones, becomes more straightforward when using a uniform time standard.
Another benefit of this approach is scalability. As Alvys continues to integrate with more providers, standardizing time zones prevents confusion and ensures accurate reporting without requiring custom logic for each provider.
How Does It Work?
All transaction times are stored in UTC within the system. When users view these transactions, they are automatically converted to the user's local time zone based on their settings. This allows users to see transaction times in a way that is most relevant to their location.
For example, a transaction timestamped as "2024-12-10 at 02:14 UTC" will appear as:
"2024-12-09 at 20:14" in Central Time (CST, UTC-6)
"2024-12-09 at 19:14" in Mountain Time (MST, UTC-7)
This time zone conversion can lead to some perceived discrepancies, especially when filtering transactions or reviewing reports. Users may need to adjust their filters by "+/- 1 day" to account for these differences.
