If you get this error and you’re not using an obviously wrong timestamp, check your units. fromtimestamp expects a timestamp in seconds, whereas it’s quite common to get timetstamps in milliseconds (e.g. I found this when trying to parse a timestamp produced from Moment.js in a calendar widget). Take the timestamp 1523443804214 – it’s 11th … Read more
Unix Time is usually a 32-bit number of whole seconds from the first moment of 1970 in UTC, the epoch being 1 January 1970 00:00:00 UTC. That means a range of about 136 years with about half on either side of the epoch. Negative numbers are earlier, zero is the epoch, and positive are later. … Read more
Unix() always returns the number of seconds elapsed since January 1, 1970 UTC. So it does not matter whether you give it time.Now() or time.Now().UTC(), it is the same UTC time, just in different places on Earth. What you get as the result is correct.
You can initialise a Date object and call getTime() to get it in unix form. It comes out in milliseconds so you’ll need to divide by 1000 to get it in seconds. (new Date(“2013/09/05 15:34:00”).getTime()/1000) It may have decimal bits so wrapping it in Math.round would clean that. Math.round(new Date(“2013/09/05 15:34:00”).getTime()/1000)
The docs mention this method: SELECT strftime(‘%s’, ‘now’); 1284248196 And this one which includes the fractional part: SELECT (julianday(‘now’) – 2440587.5) * 86400.0; 1284248196.65098 Both represent Unix Time, the number of seconds passed since January 1, 1970.
The timestamp is updated when the data that represents the directory changes. A change in a subdirectory of directory D does not change anything in the representation of D because D only points to the subdirectory, not to what’s inside it. On the other hand, creating a file in D changes the block of data … Read more
You can use the -u option of date command: date -u -u Display (or set) the date in Greenwich Mean Time (GMT-universal time), bypassing the normal conversion to (or from) local time.
The number of seconds per day are fixed with Unix timestamps. The Unix time number is zero at the Unix epoch, and increases by exactly 86400 per day since the epoch. So it cannot represent leap seconds. The OS will slow down the clock to accommodate for this. The leap seconds is simply not existent … Read more
If your data is stored in a column called ts, in a table called data, do this: select extract(epoch from ts) from data
Try: SELECT * FROM eventList WHERE `date` BETWEEN FROM_UNIXTIME(1364256001) AND FROM_UNIXTIME(1364342399) Or SELECT * FROM eventList WHERE `date` BETWEEN ‘2013-03-26 00:00:01’ AND ‘2013-03-26 23:59:59’
