addTime

Description

Returns a new timestamp by adding an interval to an existing timestamp.

Both timestamp and interval are first-class types in DataPrime, so ensure that the correct types are passed.

Syntax

Like many functions in DataPrime, addTime supports two notations, function and method notation. These interchangeable forms allow flexibility in how you structure expressions.

addTime(t: timestamp, i: interval): timestamp

(t: timestamp).addTime(i: interval): timestamp

Arguments

Example

Use case: Compute an event’s end time from its start time and duration

A log contains a start_timestamp field and a duration field in seconds. Convert the duration to an interval, then add it to the start time to calculate the event's end_timestamp.

{
  "start_timestamp": 1728582889,
  "duration": 120
}

create end_timestamp from addTime(start_timestamp, duration.toInterval('s'))

create end_timestamp from start_timestamp.addTime(duration.toInterval('s'))

Output

{
  "start_timestamp": 1728582889,
  "duration": 120,
  "end_timestamp": 1728583009
}
