T1124 - System Time Discovery

Description from ATT&CK

An adversary may gather the system time and/or time zone from a local or remote system. The system time is set and stored by the Windows Time Service within a domain to maintain time synchronization between systems and services in an enterprise network. (Citation: MSDN System Time) (Citation: Technet Windows Time Service)

System time information may be gathered in a number of ways, such as with Net on Windows by performing net time \hostname to gather the system time on a remote system. The victim's time zone may also be inferred from the current system time or gathered by using w32tm /tz. (Citation: Technet Windows Time Service) The information could be useful for performing other techniques, such as executing a file with a Scheduled Task/Job (Citation: RSA EU12 They're Inside), or to discover locality information based on time zone to assist in victim targeting.
