Snowflake offers several timestamp data types to cater to various use cases, including TIMESTAMP_NTZ (No Time Zone), TIMESTAMP_LTZ (Local Time Zone), and TIMESTAMP_TZ (Time Zone). Converting timestamps to Coordinated Universal Time (UTC) is crucial for achieving consistency across time zones, avoiding Daylight Saving Time (DST) issues, simplifying data analysis and collaboration, easing data integration, and facilitating internationalization. To convert from epoch to UTC, you can use the TO_TIMESTAMP function in Snowflake. Additionally, you can use the CONVERT_TIMEZONE function to convert TIMESTAMP_NTZ, TIMESTAMP_LTZ, and TIMESTAMP_TZ values to UTC. Understanding the differences between these timestamp types will help you choose the most suitable type for your specific data requirements.
