Local time is used throughout the web interface. It is shown in the system information bar at the bottom of the screen
and is used to set the timestamp that appears at the start of each line in the Event Log.
and is used to set the timestamp that appears at the start of each line in the Event Log.
Note that UTC timestamps are included at the end of each entry in the Event Log.
Internally, the Expressway maintains its system time in UTC. It is based on the Expressway's operating system time,
which is synchronized using an NTP server if one is configured. If no NTP servers are configured, the Expressway
uses its own operating system time to determine the time and date.
which is synchronized using an NTP server if one is configured. If no NTP servers are configured, the Expressway
uses its own operating system time to determine the time and date.
Specifying your local Time zone lets the Expressway determine the local time where the system is located. It does
this by offsetting UTC time by the number of hours (or fractions of hours) associated with the selected time zone. It
also adjusts the local time to account for summer time (also known as daylight saving time) when appropriate.
