timeadd Function

timeadd adds a duration to a timestamp, returning a new timestamp.

timeadd(timestamp, duration)

In the Packer language, timestamps are conventionally represented as strings using RFC 3339 "Date and Time format" syntax. timeadd requires the timestamp argument to be a string conforming to this syntax.

duration is a string representation of a time difference, consisting of sequences of number and unit pairs, like "1.5h" or "1h30m". The accepted units are "ns", "us" (or "µs"), "ms", "s", "m", and "h". The first number may be negative to indicate a negative duration, like "-2h5m".

The result is a string, also in RFC 3339 format, representing the result of adding the given direction to the given timestamp.

-> Breaking change note: Packer previously let you decide your own "Date and Time format" syntax. With HCL2 and for parity with Terraform, Packer will be using the RFC 3339 "Date and Time format" syntax. As a string. formatdate still allows you to format a date.

Examples

> timeadd("2017-11-22T00:00:00Z", "10m")
2017-11-22T00:10:00Z
