parseInterval

Description

Returns an interval parsed from a string representation such as 2d or 35m10s, enabling calculations with durations.

A valid string must follow these rules:

• Format: NdNhNmNsNmsNusNns where N is a non-negative integer
• At least one time unit must be present
• No unit may appear more than once (1d2d is invalid)
• Units must appear in descending order (days → nanoseconds). 1d1s is valid; 1s1d is not
• A leading - is allowed to indicate a negative interval (the only valid position for -)
• If the format is invalid, the function returns null

Syntax

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

parseInterval(string: string): interval

(string: string).parseInterval(): interval

Arguments

Example

Use case: Parse an interval string and add it to a timestamp

A log includes a timestamp and a completed_in field with a duration string. Parse the string to an interval, then add it to the timestamp to calculate the job’s completion time.

{
"timestamp": 1728763337,
"job_name": "BUILD_VIDEO",
"completed_in": "35m10s"
}

create completed_time from addTime(timestamp, parseInterval(completed_in))

create completed_time from timestamp.addTime(completed_in.parseInterval())

Output

{
"timestamp": 1728763337,
"job_name": "BUILD_VIDEO",
"completed_in": "35m10s",
"completed_time": 1728765447
}
