# What this PR does
If an OnCall template needs to contain a date relative to a date in the
alert response, currently there is no way for the template to add or
subtract time from a parsed date.
This PR adds a function that allows a time-window (e.g., 1s, 5m, 6h, 7d,
2w) to be converted into a Python timedelta, which can then be added or
subtracted from a datetime. An example usage might be:
```
{% set delta = alert.timeWindow | timedeltaparse %}
{% set time = alert.startsAt | iso8601_to_time - delta | datetimeformat('%s') %}
```
