Timezone

What is the calendar timezone?

Blotato uses your computer's local timezone. The time shown in your computer's clock is the timezone used by Blotato to schedule posts.

You can check this by creating a test post scheduled 5 minutes from now.

Scheduling via API or n8n

When you schedule posts through the API or n8n, Blotato does not know your local timezone. You must include the timezone offset in your timestamp.

Send the scheduledTime field as a full ISO-8601 string with a timezone offset:

2026-02-17T09:04:00-03:00

This tells Blotato: "publish at 9:04 AM in UTC-3 (e.g. Asuncion, Paraguay)."

If you send a timestamp without a timezone offset (for example, 2026-02-16 08:12), Blotato treats it as UTC. If your local timezone is UTC-3, the post will publish 3 hours earlier than you intended.

Examples

Goal	Correct format
9:00 AM in New York (UTC-5)	2026-02-17T09:00:00-05:00
9:00 AM in London (UTC+0)	2026-02-17T09:00:00+00:00
9:00 AM in Berlin (UTC+1)	2026-02-17T09:00:00+01:00
9:00 AM in Asuncion (UTC-3)	2026-02-17T09:00:00-03:00

Alternatively, convert your local time to UTC and append Z:

2026-02-17T12:04:00Z

Timezone in n8n + Google Sheets

If your scheduled time comes from a Google Sheet, it often has no timezone attached. Use an n8n "Date & Time" node to convert the value to ISO-8601 with the correct offset before passing it to the Blotato "Create Post" node.
