unix-timestamp

Is there an easy (single query) way to do this? I'm reading those values from a column in a table and I think that the column itself is defined as a string (can't be helped, i'm afraid). Use UNIX_TIMESTAMP ; SELECT UNIX_TIMESTAMP('2007-11-30 10:30:19'); Update: SELECT UNIX_TIMESTAMP(CAST(fieldName AS DATE)); SELECT UNIX_TIMESTAMP(STR_TO_DATE('08/05/10','%m/%d/%y')); SELECT '12/31/10', STR_TO_DATE('12/31/10', '%m/%d/%y'), UNIX_TIMESTAMP(STR_TO_DATE('12/31/10', '%m/%d/%y')) Both functions are covered here: http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html 来源： https:/

What is the best way to convert UnixTime to a date? Is there a function for it or an algorithm? Olaf Dietsche Unix time is seconds since epoch (1970-01-01). Depending on what you mean, you can convert it to a struct tm with localtime or convert it to a string with strftime . time_t t = time(NULL); struct tm *tm = localtime(&t); char date[20]; strftime(date, sizeof(date), "%Y-%m-%d", tm); As the manual to localtime states The return value points to a statically allocated struct which might be overwritten by subsequent calls to any of the date and time functions. This is what some refer to as

I have all users' birthdays stored as a UNIXtimestamp and am wanting to send out e-mails each day to users that have a birthday that day. I need to make a MySQL query that will get all of the rows that contain a birthday on today's date. It seems like this should be fairly simple, but maybe I am just overcomplicating it. This should work: SELECT * FROM USERS WHERE DATE_FORMAT(FROM_UNIXTIME(birthDate),'%m-%d') = DATE_FORMAT(NOW(),'%m-%d') Here is an answer that property takes into account leap-years and will always give you the users whose birthday is on the 29th of February at the same time as

I have a logging table that will contain millions of writes for statistical reasons. All the columns are int foreign keys. I am also going to add a timestamp column for each row. Given that DATETIME takes 8bits - I will be using int(10) unsigned to cut the storage space (and index on that column) in half. However, I'm wondering when this column would no longer work. At 3:14:07AM on 19th January 2038 the value 9,999,999,999 will be a problem for UNIX timestamps - but an unsigned int in MySQL only holds up to 4,294,967,295 and the timestamp 4294967295 is showing an invalid number in my PHP

What is the number of one second ticks between Unix time epoch (01 Jan 1970) and GPS time epoch (06 Jan 1980)? I have seen multiple answers from several sources on the web. One camp claims the answer is 315964800 , the other claims it is 315964819 . I always thought it was 315964800, but now am not so sure. I just found my software baseline has been using 315964819 for the last eight years. I have a hard time understanding how it could have been 19 seconds off and no one noticed it when we integrated our embedded devices with other devices. I think that whoever put 315964819 in the code
