Re: getting system date and system time

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

It would work.  But it might be wrong.  The problem with your technique, 
Booth, is that it's reading from the system clock twice (whereas Brian's 
was only reading from the clock once.)   The problem with reading it 
twice is that the two reads happen at slightly different times (perhaps 
2 nanoseconds later, or something like that.)

Imagine if the first call (to get the date) happened at 23:59:59 so you 
got a date of 2007-12-14.  And the second call to get the happened at 
midnight exactly (which would be 2007-12-15).   Then your database might 
contain records that say "it happened on 2007-12-14 00:00:00" which is a 
day off!

It's better to read the system clock in all one call, as Brian did. It 
doesn't change the coding significantly, and eliminates those "once in a 
while" errors that happen when the user just happened to hit enter at 
the wrong time...
