DAYLIGHT SAVINGS
Daylight Savings Enabled:
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 XW-110-
Plus
will automatically be shifted
forward by one hour between the hours of 12:00 AM – 5:00 AM 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 AM on the Daylight
Savings End
date set below. The time change is made at a random time within the previously
mentioned, five-hour time frame, in order to prevent several different devices from simultaneously
requesting a time and overwhelming the NTP server. The default setting is
Yes.
Note: Logged data includes a time stamp based upon the current time in the device, so it is possible to
duplicate log times in the spring and miss log times in the fall. To avoid confusion, many servers and
data loggers are set to remain on GMT time and do not shift for daylight savings.
Daylight Savings Start:
This is the date that daylight savings will start. Note that on this date, between the hours of 12:00 AM –
5:00 AM, the current time will be shifted forward by one hour (i.e. the time will jump from 12:02 AM
[00:02] to 1:02 AM [01:02]). By default this is set to the 2nd Sunday in March which is the date used in
the United States.
Daylight Savings End:
This is the date that daylight savings will end. On this date, between the hours of 12:00 AM – 5:00 AM,
the current time will be shifted backward by one hour (i.e. time will jump from 12:02 AM [00:02] to 11:02
PM [23:02] the day before). By default this is set to the 1st Sunday in November which is the date used
in the U.S.
