Sync With Server
This option allows the user to specify how often the time on the XW-111 will be synchronized with the
time server. When the submit button on this page is pressed, the XW-111 will immediately synchronize
with the time server. If Daily, Weekly, or Monthly options are selected, the XW-111 will thereafter re-
synchronize with the time server at the period interval specified starting at the time of day the settings
were submitted. The default value of this setting is Once (the unit will immediately sync with the NTP
server, but will not automatically sync again until power cycled).
UTC Offset
Time servers return the current time in Universal Time (GMT). It is common for many servers and data
loggers to use GMT as their official time, even when they are not located within the GMT time zone. The
default value for this field is -7 (Mountain Standard Time). For convenience, the time can be converted to
local standard time by entering the offset here. This manual cannot include the UTC Offset for all parts of
the world, but the offset for GMT time and the four major US Time zones are listed here.
GMT Time: 00:00
Eastern Standard Time: -5:00
Central Standard Time: -6:00
Mountain Standard Time: -7:00
