|
|=============== From WebEnable Design Spec Rev 3 04/11/97==================
| DISCUSSION:
|
| This implementation of this entire group is rather problematical without the
| creation of a standard. It certainly appears that many software manufacturers
| dutifully register SOMETHING in the Registry when software is installed,
| however there appears to be no rhyme nor reason to the information put into
| the Registry in leaves below the manufacturers name. Consequently, for
| installed application software, there is no easy, reliable way of mapping
| the Registry information into entries in this table.
|
| It is clear that some consistent scheme seems to be currently implemented for
| Microsoft software, however the details of extracting it from the Registry
| (and whether or not all information needed for full population of entries in
| this table is available) is not documented.
|
| Proper implementation of "hrSWInstalled" requires the creation and
| promulgation of a standard for registering ISD software (presumably in the
| Registry). Information in "hrSWInstalled" includes attributes with
| values of Object Identifiers. Webenable Inc. is prepared to work with
| Microsoft in establishing a standard for registering software in a fashion
| that allows proper implementation of the "hrSWInstalled" table.
|
| Resolution:
| Report only logo 95 compliant software initially.

| Here's the deal on this one. We've got a 64-bit FILETIME
| representation of when the Registry entry was made for the
| software. We're taking this as the install time of the software.
|
| So we convert to MS-DOS time, then to DateAndTime (in the
| 8-octet form) below:
|========================== From RFC1514 ========================
|
| DateAndTime ::= OCTET STRING (SIZE (8 | 11))
| -- A date-time specification for the local time of day.
| -- This data type is intended to provide a consistent
| -- method of reporting date information.
| --
| -- field octets contents range
| -- _____ ______ ________ _____
| -- 1 1-2 year 0..65536
| -- (in network byte order)
| -- 2 3 month 1..12
| -- 3 4 day 1..31
| -- 4 5 hour 0..23
| -- 5 6 minutes 0..59
| -- 6 7 seconds 0..60
| -- (use 60 for leap-second)
| -- 7 8 deci-seconds 0..9
| -- 8 9 direction from UTC "+" / "-"
| -- (in ascii notation)
| -- 9 10 hours from UTC 0..11
| -- 10 11 minutes from UTC 0..59
| --
| -- Note that if only local time is known, then
| -- timezone information (fields 8-10) is not present.
|
| MS-DOS records file dates and times as packed 16-bit values.
| An MS-DOS date has the following format:
| Bits Contents
| ---- --------
| 0-4 Days of the month (1-31).
| 5-8 Months (1 = January, 2 = February, and so forth).
| 9-15 Year offset from 1980 (add 1980 to get actual year).
|
| An MS-DOS time has the following format:
| Bits Contents
| ---- --------
| 0-4 Seconds divided by 2.
| 5-10 Minutes (0-59).
| 11-15 Hours (0-23 on a 24-hour clock).
