I have written some new funtions for time and date data types which can
be used to extract hour,minutes,seconds from time values, and year,
month,day from a date. There is also a time_difference and functions
to convert a time to minutes or seconds.

There are also new input/output functions for the time data type which
allow the insertion of time attributes with value 24:00:00.
This can be useful if your application needs to compute time difference
from two time values representing an elapsed time of 24 hours.

From: Massimo Dal Zotto <dz@cs.unitn.it> Here is a tar file the new directories, which substitute the old ones in contrib. Please remove the old directories array, datetime, miscutil, string and userlock before unpacking the tar file in contrib. Note that as the modules are now installed in lib/modules I install all my sql code in lib/sql. In my opinion also the other contributors should follow these rules. 1998-08-30 23:37:51 +04:00			`I have written some new funtions for time and date data types which can`
