Gets the second of a timestamp field.

ParameterTypeRequiredDefault ValueDescription
asstringoptional[a] _second The name of the output field.
field[b]stringoptional[a] @timestamp The name of the input field.
timezonestringoptional[a]   The time offset to use, for example, -01:00. If not specified, the query's offset will be used.
timezoneFieldstringoptional[a] @timezone The name of the field containing the timezone to use, if not specified the query's timezone will be used. This is ignored if the timezone parameter is passed as well. If this is not defined the timezone offset of the query will be used.

[a] Optional parameters use their default value unless explicitly set.

[b] The parameter name field can be omitted.

Extract Second From Timestamp

Get the second from a timestamp using the time:second() function

Query
logscale
time:second(timestamp, as=second)
Introduction

In this example, the time:second() function is used to extract the seconds from a specific timestamp 2025-08-27 08:51:51.312, demonstrating how to get the second value from a datetime.

Step-by-Step

  1. Starting with the source repository events.

  2. logscale
    time:second(timestamp, as=second)

    Extracts the seconds from the @timestamp field and returns the result in a new field named second. If the as parameter is not specified, the result is returned in a field named _second as default.

  3. Event Result set.

Summary and Results

The query is used to extract the seconds from a timestamp, which is useful for analyzing events at a second-level granularity.

This query is useful, for example, to analyze per-second patterns, group events by second, or investigate timing patterns within minutes.

Sample output from the incoming example data:

@timestampsecond
2025-08-27 08:51:51.31251

The result shows how the time:second() function extracts the seconds (in this case 51) from the timestamp, indicating it is 51 seconds into the minute.

For visualizing this data, consider using a Bar Chart widget to show event distribution across seconds, or a Heat Map widget to display activity patterns within minutes. The time:second() function is often used with other time functions like time:minute() and time:millisecond() for precise time analysis.
