Can someone please explain how I can parse the year, month, day, hour,
minute, and seconds from a timestamp such as '2004-01-01
01:22:15.1234'
IDL> print, a
2004-01-01 00:10:22
IDL> print, size(a, /tname)
STRING
IDL> sql_fmt = "(C(CYI4, X, CMoI2.2, X, CDI2.2, X, CHI2.2, X," + $
IDL> " CMI2.2, X, CSF7.4))"
IDL> reads, a, year, format=sql_fmt
IDL> help, year
YEAR INT = 28173
IDL> reads, a, year, month, date, hour, minute, seconds,
format=sql_fmt
% READS: End of input data encountered: A
% Execution halted at: $MAIN$
Thanks, I've blown most of the morning on this...

Take a look at
http://idlastro.gsfc.nasa.gov/ftp/pro/astro/date_conv.pro
IDL> result = date_conv(a,"V")
IDL> print,result[0]
2004
date_conv isn't *exactly* what you want, since result[1] is
"day of year (0-366)" as opposed to month and then day, but
if you take a look at the code it should be pretty straightforward
to modify for your purposes...
