Re: [PHP] Time calculation after UNIX
Use 64bit integers! They'll count up to a much higher number and will last way beyond 2038. In the database, set the correct type (INT8 in PostgreSQL, dont know about the others). Dont worry about PHP as I'm sure there'll be a few newer versions supporting wider int formats before then (if it doesn't already??) -- Shane On Wednesday 16 Jan 2002 9:33 am, Olav Drageset wrote: Hi I have a database that is supposed to last more than 30 years Could someone advice me how to calculate (add and subtract) time in a maner that willl be correct after 2030 when Unix Time stop working? ragards [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Hi Olav, I have a database that is supposed to last more than 30 years Could someone advice me how to calculate (add and subtract) time in a maner that willl be correct after 2030 when Unix Time stop working? if you are using MySQL, then use datetime or date column type. they can support date range from '1000-01-01' to '-12-31'. and for calculation, you can use MySQL function: ADDDATE() or SUBDATE() -- Jimmy Bigamy is having one spouse too many.

An excerpt from the mysql manual: --- 1.7 Year 2000 Compliance MySQL itself has no problems with Year 2000 (Y2K) compliance: MySQL uses Unix time functions and has no problems with dates until 2069 --- However, it seems to me that this is the way to go indeed, because you can always upgrade MySQL in on December 31st, 2068 (if you're 30 now, you'll be 96 then, so no problems - just leave some installation instructions your will). :-) Bogdan Jimmy wrote: Hi Olav, I have a database that is supposed to last more than 30 years Could someone advice me how to calculate (add and subtract) time in a maner that willl be correct after 2030 when Unix Time stop working? if you are using MySQL, then use datetime or date column type. they can support date range from '1000-01-01' to '-12-31'. and for calculation, you can use MySQL function: ADDDATE() or SUBDATE() -- Jimmy Bigamy is having one spouse too many.
