Time zone math without the headaches. Convert a wall-clock date and time from one zone to another with daylight saving handled correctly, ask for the current time of any zone with its offset, or list all supported zone names.
Ideal for scheduling meetings across offices, showing event times in each user local zone, and normalizing timestamps in logs and bookings.
Each endpoint returns JSON data that includes the converted date and time, local times in both source and target zones, their respective offsets, and the universal time (UTC) for the conversion.
The key fields in the response include "input" (original date/time), "from" (source zone), "to" (target zone), "utc" (universal time), "source" (local time and offset in the source zone), and "result" (local time and offset in the target zone).
The main parameters for the conversion endpoint are "input" (date and time), "from" (source time zone), and "to" (target time zone). Users must provide valid time zone identifiers for accurate conversions.
The response data is structured in a JSON format with nested objects. The main object contains fields for input, source, and result, allowing users to easily access both local times and offsets for the specified zones.
Typical use cases include scheduling meetings across different time zones, displaying event times in users' local zones, and normalizing timestamps in logs and bookings to ensure consistency across regions.
Data accuracy is maintained by following the standard worldwide zone database, which includes up-to-date daylight saving rules and time zone information, ensuring reliable conversions.
The API covers all global time zones, including major cities and regions, allowing users to convert times between any supported zones worldwide.
Users can utilize the returned data by extracting the local times and offsets for display in applications, ensuring that users see accurate times based on their respective time zones.
