Timezones in Uptime.com | Changing Timezones and What is Affected

Uptime.com localizes account timezones based on the owner’s preference. Timezones are important for coordinating everything from reporting and alerts to maintenance times. This article will discuss where to change your account timezone, what this timezone affects, and will prepare your team to utilize Uptime.com even when your workforce is distributed.

Setting or Changing Your Account Timezone


By default, Uptime.com utilizes the account owner’s timezone. In certain situations, it is useful to change this setting (such as if the account owner is not in the same timezone as the development team, or if management is done off site). 

Please Note: Administrators and Account Owners can change their preferred timezone at any time, which will affect all users associated with the account. 

Changing Timezones

Navigate to Settings > Account Details to change your timezone. 


Click Update Details to finalize your timezone selection. 

Timezone Effects


Timezones help to localize many aspects of an Uptime.com account, and affect multiple elements that include reporting and alerting functionality. Here is a brief list, along with a summation of what is affected:

  • Alerts: Alerts will display outage times in the preferred timezone. This includes emailed alerts, alert screens, Dashboard, weekly uptime report emails, and the alert history page

Important Notes Regarding Timezones


Timezone preference does not affect API usage, Integrations, or Billing/Invoices. These are all scheduled and reported according to UTC time. Note that the REST API can accept time ranges in any timezone using ISO 8601 format (e.g. 2019-02-01T12:00:00-0500), and will return data for the appropriate range as UTC times, which you can then localize as needed.
