By default, git.commit.time should be formatted with dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ" and dateFormatTimeZone = "${user.timezone}"

[tha2015]

Spring boot expects git.commit.time in the format of
yyyy-MM-dd’T’HH:mm:ssZ
(see https://docs.spring.io/spring-boot/docs/current/reference/html/howto-build.html#howto-git-info)

The maven-git-commit-id-plugin also uses default configs when generating git.commit.time value
dateFormat = yyyy-MM-dd'T'HH:mm:ssZ
dateFormatTimeZone = ${user.timezone}

Currently this Gradle plugin generates git.commit.time as a Unix timestamp value which is not very human friendly.

I suggest that we should format git.commit.id by default to a human friendly value using the below default configs:
dateFormat = yyyy-MM-dd'T'HH:mm:ssZ
dateFormatTimeZone = ${user.timezone}
