I've found this message in the bug-coreutils list. It turns out that date is parsing the + 1 as offset from UTC. This can be seen if I use different numbers in my date invocation:
Notice how the minute field stays at 01 rather than being incremented (decremented) by the value I specified.
Now, counter-intuitively, I can place the + 1 minute anywhere in the date definition, so
works as I wanted it to.
So, it is a (known) bug; it is not the bug I thought it was.
Time to mark as solved.

I know there are some posts on getting the time with milliseconds included and I realize unix may not be the best on this.

Should work in any shell, but requires GNU date, although GNU date seems only to be happy for input dates between 1902 and 2037, inclusive (49673 days).
Assume $a and $b hold two dates, e.g.
set a=2010-03-27
set b=2010-04-04

Dear all,
This should be simple but I cannot figure it out despite reading all the man pages. Could someone please help me translate this code (GNU date) to one that can be read by BSD date?:
myDate=$(date -d "$h -$l days" +%Y/%m/%d),
where h is a variable of the form DD/MM/YYYY, and l is... (3 Replies)
It's easy as pie to get the date minus one day on opensolaris:
date -d "-1 day" +"%Y%m%d"run this command on our crappy Solaris 10 machines however (which I'm guessing doesn't have GNU date running on it) and you get:

Dear all,
I have 2 questions.
I have a file with many rows which has date of the format YYYYMMDD.
1. I need to change the date to that weeks friday date(Ex: 20120716(monday) to 20120720). Satuday/Sunday has to be changed to next week friday date too.
2. After converting the date to... (10 Replies)
Why is the result of this command off (or less) by one hour
date --date "1979-10-26 +54 hours" +%Y%m%d%H
The result is
1979102805
It actually should be
1979102806
It does it with adding minutes as well and only occurs on Oct. 26, from what I can tell. What's going on here? (9 Replies)

curl_getdate(3) libcurl Manual curl_getdate(3)NAME
curl_getdate - Convert a date string to number of seconds since January 1, 1970
SYNOPSIS
#include <curl/curl.h>
time_t curl_getdate(char *datestring, time_t *now );
DESCRIPTION
This function returns the number of seconds since January 1st 1970 in the UTC time zone, for the date and time that the datestring parame-
ter specifies. The now parameter is not used, pass a NULL there.
NOTE: This function was rewritten for the 7.12.2 release and this documentation covers the functionality of the new one. The new one is not
feature-complete with the old one, but most of the formats supported by the new one was supported by the old too.
PARSING DATES AND TIMES
A "date" is a string containing several items separated by whitespace. The order of the items is immaterial. A date string may contain
many flavors of items:
calendar date items
Can be specified several ways. Month names can only be three-letter english abbreviations, numbers can be zero-prefixed and the
year may use 2 or 4 digits. Examples: 06 Nov 1994, 06-Nov-94 and Nov-94 6.
time of the day items
This string specifies the time on a given day. You must specify it with 6 digits with two colons: HH:MM:SS. To not include the time
in a date string, will make the function assume 00:00:00. Example: 18:19:21.
time zone items
Specifies international time zone. There are a few acronyms supported, but in general you should instead use the specific relative
time compared to UTC. Supported formats include: -1200, MST, +0100.
day of the week items
Specifies a day of the week. Days of the week may be spelled out in full (using english): `Sunday', `Monday', etc or they may be
abbreviated to their first three letters. This is usually not info that adds anything.
pure numbers
If a decimal number of the form YYYYMMDD appears, then YYYY is read as the year, MM as the month number and DD as the day of the
month, for the specified calendar date.

STANDARDS
This parser was written to handle date formats specified in RFC 822 (including the update in RFC 1123) using time zone name or time zone
delta and RFC 850 (obsoleted by RFC 1036) and ANSI C's asctime() format. These formats are the only ones RFC2616 says HTTP applications may
use.
RETURN VALUE
This function returns -1 when it fails to parse the date string. Otherwise it returns the number of seconds as described.
If the year is larger than 2037 on systems with 32 bit time_t, this function will return 0x7fffffff (since that is the largest possible
signed 32 bit number).
Having a 64 bit time_t is not a guarantee that dates beyond 03:14:07 UTC, January 19, 2038 will work fine. On systems with a 64 bit time_t
but with a crippled mktime(), curl_getdate will return -1 in this case.
REWRITE
The former version of this function was built with yacc and was not only very large, it was also never quite understood and it wasn't pos-
sible to build with non-GNU tools since only GNU Bison could make it thread-safe!
The rewrite was done for 7.12.2. The new one is much smaller and uses simpler code.
