1) I have mySQL 3.23 installed. I have a record with two date/times
fields in YYYY-MM-DD HH:MM:SS format. How do I find the difference
between those two date/times? (I would also like to know it with
seconds left off.)
2) Let's say I have two records each with a date/time field in
YYYY-MM-DD HH:MM:SS format. How do I find the difference in date/times
when each field is in a different record?
Thanks,

Hi
I am trying to find difference between two time values in hours. I have
tried the following?
? dateDiff("h", #23:00:00#, #23:00:00#) gives 0 as expected.
? dateDiff("h", #00:00:00#, #23:00:00#) gives 23??? should it not be 1 as
00:00:00 (12 midnight) is only one hour after 23:00:00 (11 pm)?

Hi,
I'm really sorry to post this as I know it must have been asked
countless times before, but I can't find an answer anywhere.
Does anyone have a snippet of JavaScript code I could borrow which
calculated the difference in years and days between two dates, and
takes leap years into account?
I'm calculating the difference in the usual way, i.e....

For the purpose of finding someone's age I was looking for a way to
find how the difference in years between two dates, so I could do
something like:
age = (date.today() - born).year
but that didn't work (the timedelta class doesn't have a year
accessor).
I looked in the docs and the cookbook, but I couldn't find anything, so

Anyone know how to calculate the difference between two times
displayed in two textboxes?
I'm starting out with two textboxes: "txtCallTimeBegins" &
"txtCallTimeEnds"
this yielded: 6/7/2007 2:40:50 PM & 6/7/2007 2:45:04 PM respectively.
First I have coverted these to two additional textboxes to hold only
the time, not the date using:
=TimeValue() & =TimeValue()

I am trying to calculate elapsed travel times for flights. My plan is
to enter the local departure time, the departure city and the local
arrival time and city. These times would be standardised to GMT and a
date difference calculated which would be the theoretical elapsed time
of the flight
I have one Table called Cities which has the name of the city and the
difference from GMT eg Sydney is 10 (ie 10 hrs ahead of GMT), LA is -7
ie 7...

Hello,
I have 2 time fields dynamically generated in format "m/d/y H:m".
Could someone show me a good function to calculate the time interval
difference in minutes? I played with strtotime() but but that only
gave me difference in hours and only if the times were on the same day
(after wrapping with date() function). TIA

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
