Added NTP Client to the packages

We often ran into timing issues in the workflow (e.g. commit, push and git fails with file TS in the future), and
within the architecture as well (logging times off, etc.).

Therefore I added the `ntp` package.

*note*: this is an alternative for #85.
Merge pull request #104 from Springest/ntp-package
