Editing Clock synchronization (section)

==Problems==
As a result of the difficulties managing time at smaller scales, there are problems associated with [[clock skew]] that take on more complexity in [[distributed computing]] in which several computers will need to realize the same global time. For instance, in [[Unix]] systems, the ''[[make (software)|make]]'' command is used to [[compile]] new or modified code and seeks to avoid recompiling unchanged code. The ''make'' command uses the clock of the machine it runs on to determine which source files need to be recompiled. If the sources reside on a separate [[file server]] and the two machines have unsynchronized clocks, the ''make'' program might not produce the correct results.<ref>{{cite web |url=http://www.dsn.jhu.edu/~platania/index_files/clock_sync.pdf |page=11 |title=Clock Synchronization |author=Marco Platania |date=2018-06-03}}</ref>

Synchronization is required for accurate reproduction of [[streaming media]]. Clock synchronization is a significant component of [[audio over Ethernet]] systems.
