Thank you for your contribution! This command was missing indeed and you brought a good and simple example usage :)

I have some suggestions about the guidelines we generally follow. See details in https://github.com/tldr-pages/tldr/blob/main/contributing-guides/style-guide.md.

I think https://manned.org/ntpd is more adequate for the "More information" link, because the linux version has some differences. For example, you used long options that are not on https://www.ntp.org/documentation/4.2.8-series/ntpd/.

The build for this PR failed with the following error(s):

pages/linux/ntpd.md:9 MD032/blanks-around-lists Lists should be surrounded by blank lines [Context: "- Synchronize system time with..."]
pages/linux/ntpd.md:9: TLDR007 Example descriptions should be surrounded by empty lines

Please fix the error(s) and push again.

Yeah, I hesitated on that but wanted to get to the "root source" of information, but I guess that if the tldr page has linux-specific options, the manned page is better

The previous URL pointed to the specification, while the current URL points to the implementation documentation, so it is more accurate about the command usage.

LGTM!

Thank you for your your quick fixes and, again, for your contribution :)
