This article summarizes how time zones are handled in Voiso and helps you troubleshoot apparent discrepencies between reports. ## Introduction By design, Voiso displays dates and times in the time zone that best reflects the user's requirements. Important If you encounter difficulties reconciling the dates and times between your invoices, billing reports, statements, and historical reports or the CDR, please ensure that you convert the dates and times to match the time zone of the billing report. The **Billing** page, including billing reports, invoices and statements, uses UTC so that an accountant or manager has a consistent, standardized reference point. There is no need to reconsile different time zones and daylight savings, which can be confusing. Using UTC ensures that reports are uniform across all locations of your business. The **Historical reports** pages use the time zone of the contact center to track the daily activities of agents and queues. This enables supervisors and managers to view trends according to the business hours of the contact center. The **Call Detail Records** and **Call Details** pages are designed to display interactions in the time zone of the user. This ensures that supervisors, analysts, and managers can easily review all interactions listed in the Call Detail Records, regardless of the time or location of the interaction, with the timestamps adjusted to their own time zone for seamless comparison. The following sections describe how time zones are employed in the different Voiso UIs. ## UTC Coordinated Universal Time (UTC) is the standard the world uses to regulate clocks and time. Voiso employs UTC to denote the date and time of interactions, as well as user and system activities. [Billing](/v1/docs/administration-billing) reports, [historical reports](/v1/docs/reporting-historical-reports-overview), invoices, and statements are tracked and presented in UTC. ## Contact center time zone [Administrators](/v1/docs/users-users) specify the time zone of the contact center on the **[System settings](/v1/docs/administration-system-settings)** page. The contact center time zone is used for the following [historical reports](/v1/docs/reporting-historical-reports-overview): | Report | Period | | --- | --- | | [Agent List](/v1/docs/reporting-agent-list) | From the beginning of the first selected day (00:00:00) to the end of the last selected day (23:59:59). | | [Inqueue Abandons](/v1/docs/reporting-in-queue-abandons) | From the beginning of the selected day (00:00:00) to its end (23:59:59). | | [Inqueue Abandons - Per Hour](/v1/docs/reporting-in-queue-abandons-per-hour) | Selected hours. | | [Redial Counter](/v1/docs/reporting-redial-counter) | From the beginning of the selected day (00:00:00) to its end (23:59:59). | | [Agent List - Per Hour](/v1/docs/reporting-agent-list-per-hour) | Selected hours. | | [ASR by Country](/v1/docs/reporting-asr-by-country) | From the beginning of the first selected day (00:00:00) to the end of the last selected day (23:59:59). | | [ASR per Caller ID](/v1/docs/reporting-asr-per-caller-id) | From the beginning of the first selected day (00:00:00) to the end of the last selected day (23:59:59). | | Billing Report | From the beginning of the first selected day (00:00:00) to the end of the last selected day (23:59:59). | | [Sensitive Data Access Report](/v1/docs/reporting-sensitive-data-access-report) | From the beginning of the first selected day (00:00:00) to the end of the last selected day (23:59:59). | | [Wrap-up Codes](/v1/docs/reporting-wrap-up-codes) | From the beginning of the first selected day (00:00:00) to the end of the last selected day (23:59:59). | ## User's time zone A time zone is assigned to each [user's profile](/v1/docs/users-users) when it is created. The user's time zone is used for the following user interfaces: - [Call Detail Records](/v1/docs/reporting-cdr) - [Call Details](/v1/docs/cdr-search-results) - [Agent Panel](/v1/docs/agent-panel) - [Omnichannel workspace](/v1/docs/omnichannel-workspace-overview) ### Call Detail Records The **Call Detail Records** page lists the interactions that a specific user role, such as a supervisor or an administrator, is permitted to view. Interactions and the date and time of their associated events and activities are stored by Voiso using UTC. However, when you view an interaction on the **Call Detail Records** page, Voiso displays the interaction date and time using your time zone, not the time zone of the agent who handled the interaction. An area of the world that observes a uniform standard time for legal, commercial, and social purposes. Time zones commonly follow the boundaries between countries and their subdivisions instead of following evenly spaced divisions on the globe for the convenience of keeping a consistent time. UTC, or Coordinated Universal Time, is the time standard the world uses to regulate clocks and time. It serves as a reference for various time zones. It is not affected by daylight saving time. ## Related - [Billing](/administration-billing.md) - [Historical reports overview](/reporting-historical-reports-overview.md) - [Call Detail Records overview](/reporting-cdr.md) - [Agent Panel](/agent-panel.md) - [Omnichannel Workspace Overview](/omnichannel-workspace-overview.md)
