This document lists requirements for applications developed with the Time Zone API. Note that use of the Time Zone API is governed by your Agreement with Google.
Pre-Fetching, Caching, or Storage of Content
Applications using the Time Zone API are bound by the terms of your Agreement with Google. Subject to the terms of your Agreement, you must not pre-fetch, index, store, or cache any Content except under the limited conditions stated in the terms.
Displaying Time Zone API results
You can display Time Zone API results on a Google Map, or without a map. If you want to display Time Zone API results on a map, then these results must be displayed on a Google Map. It is prohibited to use Time Zone API data on a map that is not a Google map.
Displaying the Google logo and attributions
If your application displays data on a Google Map, then the Google logo will be included and may not be altered. Applications that display Google data on the same screen as a Google Map are not required to provide further attribution to Google.
If your application displays data on a page or view that does not also display a Google Map, you must show a Google logo with that data. For example, if your application displays Google data on one tab, and a Google Map with that data on another tab, the first tab must show the Google logo. If your application uses search fields with or without autocomplete, the logo must be displayed inline.
The Google logo should be placed in the bottom left corner of the map, with the attribution information placed in the bottom right corner, both of which should be on the map being presented as a whole and not below the map or another place within the application. The following map example shows the Google logo in the lower left of the map, and the attribution in the lower right.

The following zip file contains the Google logo in the correct sizes for desktop, Android, and iOS applications. You may not resize or modify these logos in any way.
Don't modify the attribution. Don't remove, obscure, or crop out the attribution information. You cannot use Google logos inline (for example, "These maps are from [Google_logo]").
Keep the attribution close. If using screenshots of Google imagery outside of direct embeds, include the standard attribution as it appears in the image. If necessary, you may customize the style and placement of the attribution text, so long as the text is within close proximity of the content and legible to the average viewer or reader. You may not move the attribution away from the content, such as to the end of your book, the credits of your files or show, or the footer of your website.
Include third-party data providers. Some of the data and images on our mapping products come from providers other than Google. If using such imagery, the text of your attribution must say the name "Google" and the relevant data provider(s), such as "Map data: Google, Maxar Technologies." When there are third-party data providers cited with the imagery, only including "Google" or the Google logo is not proper attribution.
If you're using Google Maps Platform on a device where the attribution display is not practical, please contact the Google sales team to discuss licenses appropriate to your use case.
Style guidelines for Google attribution
Following are style guidelines for Google attributions in CSS and HTML if you're not able to use the downloadable Google logo.
The amount of clear space around the lockup should be equal to or greater than the height of the "G" in Google.
The space between the attribution copy and the Google logo should be half the width of the "G".
The byline should always be clear, legible, and appear in the right color variation for a given background. Always be sure to provide enough contrast for the logo variation that you select.
Use Google Material Gray 700 text on a white or light background that uses a range of 0%–40% maximum tint of black.
#5F6368 RGB 95 99 104 HSL 213 5 39 HSB 213 9 41
On darker backgrounds, and over photography or non-busy patterns, use white text for byline and attribution.
#FFFFFF RGB 255 255 255 HSL 0 0 100 HSB 0 0 100
Use the Roboto font.
The following CSS, when applied to the text "Google," would render "Google" with the appropriate font, color, and spacing on a white or light background.
font-family: Roboto; font-style: normal; font-weight: 500; font-size: 16px; line-height: 16px; padding: 16px; letter-spacing: 0.0575em; /* 0.69px */ color: #5F6368;
