The awk statement doesn't seem to be working the way you intend it to.
1. Keep date in this format for easier numeric comparison: yyyymmddhhmiss (20120220034005). Two such numbers are easier for comparison.
2. If date is in this format: "2012-02-20 03:40:05", how can you compare it with some other date in the same format using > and < symbols?
3. When you say $0 in awk, it refers to the whole line. I see that log.0 file contains lines in this format: "2012-02-18 22:18:06.768 | STATUS:SUCCESS", so you're trying to compare this whole line with $a and $b.
4. You can reduce this line to "2012-02-18 22:18:06" by defining the field separator as "." and taking $1 into account. And further reduce it to "20120218221806" by removing hyphen and colon.

dp
DP(8) [nmh-1.5] DP(8) NAME
dp - parse dates 822-style SYNOPSIS
/usr/lib/mh/dp [-form formatfile] [-format string] [-width columns] [-version] [-help] dates ... DESCRIPTION
Dp is a program that parses dates according to the ARPA Internet standard. It also understands many non-standard formats, such as those produced by TOPS-20 sites and some UNIX sites using ctime(3). It is useful for seeing how nmh will interpret a date. The dp program treats each argument as a single date, and prints the date out in the official 822-format. Hence, it is usually best to enclose each argument in quotes for the shell. To override the output format used by dp, the -format string or -format file switches are used. This permits individual fields of the address to be extracted with ease. The string is simply a format string and the file is simply a format file. See mh-format(5) for the details. Here is the default format string used by dp: %<(nodate{text})error: %{text}%|%(putstr(pretty{text}))%> which says that if an error was detected, print the error, a `:', and the date in error. Otherwise, output the 822-proper format of the date. FILES

None SEE ALSO
ap(8), Standard for the Format of ARPA Internet Text Messages (RFC-822) DEFAULTS
`-format' default as described above `-width' default to the width of the terminal CONTEXT
None BUGS
The argument to the -format switch must be interpreted as a single token by the shell that invokes dp. Therefore, one must usually place the argument to this switch inside quotes. MH.6.8 11 June 2012 DP(8)
