Not sure what exactly your use case is, but if you just want the current
(at the time of alert evaluation) Unix timestamp in an annotation, you
should be able to do:
{{ with query "time()" }}{{ . | first | value }}{{ end}}
Note that the "Alert" struct on the Alertmanager templating side will also
have timestamp fields on it that tell you when an alert first started
firing, and when it will expire if it's no longer sent from Prometheus:
