VHDL evaluating B GT A

So I stop screwing this up over and over,

Method for determinging A GT B for two unsigned integers using standard subtractor in VHDL:

where f(x,y) = x-y = x + 2's complement(y),

carry out of f(B-A) shows B > A. not f(A-B).

Examples:

1) is 70128 GT 65535?
for 24 bit case,
B = 70128 = x0111F0
A = 65535 = x00FFFF, 2s_comp(B) = xFF0001

B - A = x0111F0 + xFF0001 = x10011F1, carry out is 1, remainder = B-A = 4593

2) is 32768 GT 65535?
for 24 bit case,
B = 32768 = x008000
A = 65535 = x00FFFF, 2s_comp(B) = xFF0001

B - A = x008000 + xFF0001 = xFF8001, carry out is 0, remainder = B-A = -32767

Excel: Reformatting timestamps to get a graph with time on the x axis

Time column is in decimal seconds from some completely random timebase, which I took one calibration of.

Created a column with format "Time" of type hh:mm:ss. Formula for that column was:

=TIMEVALUE(TEXT("8:21:00 AM"+(A2 - 906897)/86400, "h:mm:ss"))

i.e. A2 contains a time in seconds, at 8:21 AM the seconds were 906897, and the conversion factor is expecting decimal hours (86400 seconds per hour). Converting it with TIMEVALUE produces fraction of a day, but that is then displayed properly due to the cell formatting.

This does not address the case of crossing a date boundary. Date conversion functions are not useful because the only cell formats available for date do not include seconds.
