![]() ![]() The _time field is stored in UNIX time, even though it displays in a human readable format. The following example creates a single result using the makeresults command. | eval starttime=strftime(now(),"%Y-%m-%dT%H:%M:%S.%Q")įor more information about date and time variables, see Date and time format variables. For the strftimevalues, the now() function is used to generate the current UNIX time and date and time variables are used to specify the ISO 8601 timestamp format The following example creates a new field called starttime in your search results. If the _time field value is 11:48:23, the value returned in the hour_min field is 11:48. | eval hour_min=strftime(_time, "%H:%M") The following example returns the hour and minute from the _time field. In these results the _time value is the date and time when the search was run.įor a list and descriptions of format options, see Date and time format variables. The results appear on the Statistics tab and look like this: The following search uses the pow function to convert from nanoseconds to seconds: To convert from nanoseconds to seconds, divide the number by 10^9.To convert from microseconds to seconds, divide the number by 10^6.To convert from milliseconds to seconds, divide the number by 1000 or 10^3.You can use the pow function to convert the number. If the time is in milliseconds, microseconds, or nanoseconds you must convert the time into seconds. Use the first 10 digits of a UNIX time to use the time in seconds. This function takes a UNIX time value as the first argument and renders the time as a string using the format specified. The offset -2h is processed first, followed by the snap-to time | where _time>relative_time(now(), AND _time,) Description ![]() | eval n=relative_time(now(), following example specifies an earliest time of 2 hours ago snapped to the hour and a latest time of 1 hour ago snapped to the hour. 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. ![]()
