Return Value: Returns the string "microsec sec" by default, where sec is the number of seconds since the Unix Epoch (0:00:00 January 1, 1970 GMT), and microsec is the microseconds part. The float value represents seconds. Since the specs (now) say milliseconds, you should multiply by 1000. The reason is that on 32 bit systems, PHP’s integer is also 32 bits and is not large enough to contain the timestamp including milliseconds and microseconds. Each sentence is also delayed from the real UTC time by … 2014-02-10 13:54:30.123456). See also Linux – Is gettimeofday() guaranteed to be of microsecond resolution. How can I do it?

Posted by: admin The value in the timestamp column does not change, whereas the value in the timestamptz column is adjusted to the new time zone of 'America/New_York'.. Generally, it is a good practice to use the timestamptz datatype to store the timestamp data.. PostgreSQL timestamp functions. My implementation is different than the original posters, for very specific reasons. Unix Time. However, with some additional configuration, you can update any timestamp/datetime column on any event a table publishes. Leap seconds tend to cause trouble with software. The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z).Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but 'epoch' is often used as a synonym for Unix time. Learn how to use it with some examples in this article. i.e. 10k will give you accuracy of 1/10ms = 100μs. Inaccuracy of 15 meters with photo timestamp granularity of 1 second is huge deviation. php – Symfony: How to encrypt/decrypt route parameters automatically? Like it prints one or two digits less. Those object are being generated on-the-fly and depending on dynamic content. I wanted a timestamp in a specific format, that could be obtained from a function repeatedly. Let's add on to the code we already wrote in the last section. I think you just need to use this function to get a Timestamp with micro seconds in PHP: Use it as shown in the following link, following code snippet shows you how I’d altered it according to be helpful to your question: And also for reference regarding to that microtime() PHP function, please visit and read this PHP manual page. timestamp = GetGlobalAA().util.ToMilliseconds(time) print timestamp part1 = Int(timestamp / 1000000).toStr() part2 = Str(timestamp MOD 1000000) print part1 print part2 timeStampString = part1 + part2 print timeStampString What is epoch time?
