This function takes a UNIX time as the first argument and a relative time specifier as the second argument and returns the UNIX time value of applied to. | chart count by _time relative_time(,) Description | where (eventHour=curHour and eventMin > curMin - 30) or The event timestamp, in the _time field, is used to calculate the event hour (eventHour) and event minute (eventMin). You use the now() function to calculate the current hour (curHour) and current minute (curMin). If you are looking for events that occurred within the last 30 minutes you need to calculate the event hour, event minute, the current hour, and the current minute. | eval n=relative_time(now(), Extended example

See How to specify relative time modifiers. This example uses a "snap-to" time modifier to snap to the the start of the day. The following example determines the UNIX time value of the start of yesterday, based on the value of now(). You can use this function with the eval, fieldformat, and where commands, and as part of eval expressions. If you want to return the UNIX time when each result is returned, use the time() function instead. When used in a search, this function returns the UNIX time when the search is run. The time returned by the now() function is represented in UNIX time, or in seconds since Epoch time. The now() function is often used with other data and time functions. This function takes no arguments and returns the time that the search was started. In addition to the functions listed in this topic, there are also variables and modifiers that you can use in searches. The following list contains the functions that you can use to calculate dates and time.įor information about using string and numeric fields in functions, and nesting functions, see Evaluation functions.
