November 5, 2026 Since October 21, 2026, all dates and times in Tapfiliate are in UTC, so you, your team, and your affiliates see the same numbers for any period. This article explains what changed and what it means for your reports. ## In this article: * [Why one time zone](#h_why) * [Your time zone setting](#h_check) * [What changed on October 21](#h_what_you_see) * [What stays the same](#h_same) * [FAQ](#h_faq) * [Next Steps](#h_next) ## Why One Time Zone Before October 21, 2026, Tapfiliate stored a time zone for each user. An account owner, a team member, and an affiliate could each see a day that started at a different hour. That's how the same period could show different totals to you and to your affiliate.\ Since October 21, every day in Tapfiliate starts at 00:00 UTC for everyone. One period, one total. ## Your Time Zone Setting The Time zone field in Settings → Account → General shows UTC and can't be changed. If your profile used a different time zone before October 21, your reports now count days in UTC, as described below. ## What Changed on October 21 ### In your dashboard * Reports, filters, and exports count days and months in UTC. A day starts at 00:00 UTC, for example 8 pm the day before in New York or 9 am in Tokyo. * Past periods are counted in UTC too, because Tapfiliate calculates reports on the fly. A few conversions made near midnight may now show on the day before or after, so totals for a past month can differ slightly from an export you made earlier. * Bonus periods close in UTC. Around the start of the bonus period that is open on October 21, a few hours may count toward both the previous and the current period, or toward neither. New to bonuses?

The use\_profile\_timezone parameter no longer has any effect. * Postbacks that pass conversion\_created\_at, customer\_created\_at, or click\_time send them in UTC (+00:00). The moment is the same, only the notation changes. If your affiliates read only the date from these values, you may want to let them know. ## What Stays the Same Commissions you've already earned, approved, or paid stay exactly as they are. So do your invoices and payouts. Tapfiliate doesn't add, remove, or count any commission twice. Only the hours around midnight move to a different day. ## FAQ ### ❓ Why do my totals for last month differ from my old export? Tapfiliate now counts that month in UTC, so conversions made near midnight may fall on the day before or after. To compare figures, export the old period again so both are counted in UTC. ### ❓ Can I switch back to my own time zone? Not at the moment. One time zone keeps your numbers identical to your team's and your affiliates'. If your workflow needs a different time zone, tell us about your case at [support@tapfiliate.com](mailto:support@tapfiliate.com). We'd like to hear how you use it. ### ❓ Do my affiliates see the change? Yes. Your affiliates see all dates in UTC too, and Tapfiliate no longer asks them for a time zone at sign-up. ### ❓ Does this change my billing? No. Your Tapfiliate subscription was already billed in UTC. *** **💬 Still need help?**\ Contact us at [support@tapfiliate.com](mailto:support@tapfiliate.com) or in the chat in your account.
