Updating clock serbian dating website
The ntpd algorithms discard sample offsets exceeding 128 ms, unless the interval during which no [absolute value of] sample offset is less than 128 ms exceeds 900s.The first sample after that, no matter what the offset, steps the clock to the indicated time.We can do this via Java Script's Now that we have the three component values of our current time, let's format them into a nice string for displaying in the Web page.We want it to be in the format "HH: MM: SS XX", where XX is either "AM" or "PM" (assuming we're after a 12-hour clock format).
After that, ntpd will exit if the limit is exceeded. both from Natale Well, I am running a raspbian (debian wheezy) on my raspberry pi, which doesn't have the hwclock.
In practice this reduces the false alarm rate where the clock is stepped in error to a vanishingly low incidence.
Normally, ntpd exits if the offset exceeds the sanity limit, which is 1000 s by default.
I am running Ubuntu on an ARM based embedded system that lacks a battery backed RTC. Thus, I use the NTP service to update the time to the current time.
I added the following line to $ date ; sudo service ntp stop ; sudo ntpdate -s gov ; sudo service ntp start ; date Thu Jan 1 UTC 1970 * Stopping NTP server ntpd [ OK ] * Starting NTP server [ OK ] Thu Feb 14 UTC 2013 notice the '-b' flag on ntpdate.

First we'll add a leading zero to the minutes and seconds values, if required: , to "AM" or "PM" as appropriate, and subtract 12 from the hours component, if required, to convert it to 12-hour format.
