MSDOS time/date encoding in php
Hi all
I am trying to set the last modified date/time of individual files in a zip
file.
According to the specification (http://www.pkware.com/appnote.txt), date/time
are two bytes each, and use standard msdos date/time encoding.
Does anybody have a clue to this?
With kind regards

Yeah that's the class I used as base to extend.
I don't have time to wait for the author to update his class, and I am quite capable of implementing the encoding once I get the details...

Thanks my man!
MS DOS Date Time Format
There is two additional data types witch place is here. MS DOS Date format and MS DOS Time format.
MS-DOS date
A date in the format used by MS-DOS. The date is a packed 16-bit (2 bytes) value in which bits in the value represent the day, month, and year.
MS-DOS time
A time in the format used by MS-DOS. The time is a packed 16-bit (2 bytes) value in which bits in the value represent the hour, minute, and second.
so msdos date time is 32 bits (4 bytes - 2 bytes(16 bits) for time and 2 bytes for date)
first 16 bits ( 1st byte)
0-4 - seconds
5-10 - minutes
11-15 -hours
second 16 bits
16-20 day (1 -31)
21-24 month (1-12)
25-31 year ( number of years since 1980) ==> so you get a year by addin 1980 to value of this 4 bits
