Time zones
Time zones that have the Country/City format are primary time zone IDs. Other time zone IDs are links to the primary time zone. For example, US/Pacific is a link to the America/Los_Angeles time zone.
Both America/Los_Angeles and US/Pacific represent Pacific Standard Time with the same zone offset and Daylight Savings Time (DST) schedule.
Other than the representation, there is no impact on date and time functionality.
Facts
All times are stored in Coordinated Universal Time (UTC) and appear globally based on the system time zone. However, times appear to users in their local time zone, according to their user preference settings. Learn more about Time Zones Representations

Resolution
In the absence of a default time zone for the user or the system, the JVM (Java Virtual Machine) reads default time zone information from the machine and depending on how the machine is configured, it might return US/Pacific or America/Los_Angeles.
ServiceNow recommends that admins configure their system with a default timezone using the glide.sys.default.tz property to avoid system dependencies.
