epoch

How can I convert UTC date-time string (e.g. 2011-03-29 17:06:21 UTC ) into Epoch (milliseconds) in javascript? If this is not possible, is there any way to compare (like <, >) UTC date time strings? Note that UTC date strings can be compared lexicographically, like strings, since the higher order values appear leftmost in the string. var s1 = '2011-03-29 17:06:21 UTC' , s2 = '2001-09-09 01:46:40 UTC'; s1 > s2; // => true s2 > s1; // => false You can extract the date fields from your example string and return the number of milliseconds by using the Date.UTC method: var getEpochMillis =

Similar to the timestamps given on this website: http://www.epochconverter.com/ Does DateTime have a method for that?

This question already has an answer here: Convert UTC Epoch to local date 15 answers i have a json file that returns "date_created":"1273185387" in epoch format i want to convert it to something like this Thu, 06 May 2010 22:36:27 GMT any script to do this conversion? var myObj = $.parseJSON('{"date_created":"1273185387"}'), myDate = new Date(1000*myObj.date_created); console.log(myDate.toString()); console.log(myDate.toLocaleString()); console.log(myDate.toUTCString()); http://jsfiddle.net/mattball/8gvkk/ Try the below code... var myDate = new Date( your epoch date *1000); alert(myDate

I would like to get the current timestamp and print it out using fprintf . For 32-bit systems: fprintf(stdout, "%u\n", (unsigned)time(NULL)); For 64-bit systems: fprintf(stdout, "%lu\n", (unsigned long)time(NULL)); Is just casting the value returned by time() #include <stdio.h> #include <time.h> int main(void) { printf("Timestamp: %d\n",(int)time(NULL)); return 0; } what you want? $ gcc -Wall -Wextra -pedantic -std=c99 tstamp.c && ./a.out Timestamp: 1343846167 To get microseconds since the epoch, from C11 on, the portable way is to use int timespec_get(struct timespec *ts, int base)

I want to convert a given time into epoch(time_t) and vice versa. can anyone tell what is the routine or algorithm for this? Thanks Update epoch_strt.tm_sec = 0; epoch_strt.tm_min = 0; epoch_strt.tm_hour = 0; epoch_strt.tm_mday = 1; epoch_strt.tm_mon = 1; epoch_strt.tm_year = 70; epoch_strt.tm_isdst = -1; double nsecs = difftime(curtime, basetime);//current time from system, I converrting it to struct tm but this always return 32399 for some reason. You should cast it to a long int instead of int . long int t = static_cast<long int> time(NULL); An int might not be enough to hold the time, for
