timeadd adds a duration to a timestamp, returning a new timestamp.
In the Packer language, timestamps are conventionally represented as
strings using RFC 3339
"Date and Time format" syntax.
timeadd requires the
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
"1h30m". The accepted
"h". The first
number may be negative to indicate a negative duration, like
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.
