When you specify a time in your search, either by using the time range picker or using time modifiers, the time that you specify is converted into UNIX time for processing. However, for display purposes the values in the _time field are shown in a human-readable format. The values in the timestamp field in the sample data file are converted to UNIX time and stored in the _time field when the data is indexed. Let's use a set of test data that contains 35 events with various timestamps. When data is indexed and added to your Splunk instance, the Splunk indexer assumes that any timestamps in the data are in the same time zone as your Splunk instance. For example, the United Kingdom uses GMT for most of the year, but switches to British Summer Time (BST) during the summer months. However, some of the countries that use GMT switch to different time zones during their DST period.
However GMT is a time zone and UTC is a time standard. GMT (Greenwich Mean Time) is sometimes confused with UTC (Coordinated Universal Time).
This moment in time is sometimes referred to as epoch time. UNIX time is the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), 1 January 1970. If your data does not have timestamps, the time at which your data is indexed is used as the timestamp for your events. Regardless of how time is specified in your events, timestamps are converted to UNIX time and stored in the _time field when your data is indexed. When the United States returns to Standard time, the -8 offset equates to the Pacific Standard Time (PST). San Francisco is in the Pacific timezone. The -0700 in the timestamp equates to the -7 in UTC-7.ĭuring Daylight Savings Time (DST) in the United States, the -7 offset equates to the Pacific Daylight Time (PDT). For example T11:45:30-07:00 could be expressed as UTC-7. Sometimes you might see a timestamp expressed as UTC-7 or UTC+3, which is UTC with the offset from GMT. The local time is interpreted as the same time zone as the Splunk indexer where the data is indexed. US Pacific Daylight Time, the timezone where Splunk Headquarters is located.Ī timestamp with an offset from GMT (Greenwich Mean Time)Ī timestamp expressed in UTC (Coordinated Universal Time) The timestamp might be in one of several formats, as shown in the following table: When data is indexed, the Splunk indexer looks for a timestamp in each event. Spanish: ET - Tiempo del Este, ET - Zona SuresteThe Splunk platform processes time zones when data is indexed and when data is searched. Other major cities in the area are Toronto, Montreal, Brooklyn, Borough of Queens. Principal Cities: The largest city in the EST timezone is New York City from USA with population about 8.175 million people.

Major professional sports leagues MLB, NBA, NFL and NHL also provide their game times in Eastern Time, even if teams are from outside of Eastern Time.Ĭountries: It is used in following countries: Bahamas, Canada, Haiti, Jamaica, Cayman Islands, Mexico, Panama, Turks & Caicos Is, United States. In the United States nationally televised programs, evening newscasts, talent and awards shows, and any other nationally televised event that airs live on American television during prime time and on the weekends are broadcast live in the Eastern Time Zone. states in the eastern part of the contiguous United States including the capital city Washington D.C., the most populous city New York and half of the country’s population. ET is not static but switches between EDT and EST.ĮT is also used somewhat as a de facto official time for all of the United States because it encompasses 17 U.S. Eastern Time (ET) is a general term used to describe the areas that observe either the Eastern Standard Time (EST) or Eastern Daylight Time (EDT) in the United States and Canada.
