Sync With Server
This option allows the user to specify how often WebRelay-10 Plus™ time will be synchronized with
the time server. When the submit button on this page is pressed, WebRelay-10 Plus™ will
immediately synchronize with the time server. If Daily, Weekly, or Monthly options are selected,
WebRelay-10 Plus™ will thereafter re-synchronize with the time server at the period interval
specified starting at 12:00 AM (00:00).
The exact time the NTP Request occurs is 12:00 AM (00:00) plus the minute equivalent of the last
two digits in the models serial number. For example, if the last two digits in the model's serial
number were -09, the NTP Request will occur 9 minutes after 12:00 AM. The default value of this
setting is Once (the unit will immediately sync with the NTP server, but will not automatically sync
again).
Sync on Power Up
When this option is set to
Yes
,
WebRelay-10 Plus™ will be synchronized with the time server each
time it is powered.
Note: If WebRelay-10 Plus™ will lose power on a frequent basis, it may be beneficial to set this
option to
No
; some servers are configured to dis-allow access from client devices that excessively
request their services. The default value of this setting is
No.
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: 0
Eastern Standard Time: -5
Central Standard Time: -6
Mountain Standard Time: -7
Pacific Standard Time: -8
Daylight Savings
In many parts of the United States and in some other countries, the time is shifted forward by one
hour during the summer months. This is an effort to conserve energy by making the daylight last
longer into the evening hours. If this option is set to
Yes
, the time on WebRelay-10 Plus™ will
automatically be shifted forward by one hour between the hours of 12:00 AM – 5:00 PM on the
Daylight Savings Start
date set below, and it will shift back to standard time between the hours of
12:00 AM – 5:00 PM on the Daylight Savings End
date set below. The time change is made at a
