Here's a korn shell way to do it. You'll have to add your timezone info near the bottom. I live in CST zone so I don't care about the others.
Code:
##*******************************************************************************
## Script epoch
## Purpose Take date in formatted string as an argument and coverts it

## Usage ./epoch Aug 25 23:59:59 2007 GMT

lunar
lunar(1) General Commands Manual lunar(1)NAME
lunar (version 2.2) - a calendar conversion utility
SYNTAX
lunar [ -h ] [ -b ] [ -i ] [ -l ] year month day [ hour ]
DESCRIPTION
The program performs date conversion between the Gregorian Solar Calendar (SC) and the Chinese Lunar Calendar (LC). Given a date in either
calendar, the program also outputs the corresponding "shengxiao" (animal of the year) and "ganzhi" characters. The date range currently
covered is from about 1900 A.D. to 2049 A.D.
For the sake of convenience, we choose the convention such that the solar and lunar year numbers of the first day of a lunar year are the
same. For example, SC 1991.2.15 is LC 1991.1.1, while SC 1991.2.14 is LC 1990.12.30. Moreover, we choose the convention such that the
solar and lunar hour numbers (in 24-hour clock) of a date are the same, although a lunar day starts at 23:00 of a solar day. This means
that SC 1991.2.15.23 is LC 1991.1.2.23, while SC 1991.2.16.0 is LC 1991.1.2.0, and SC 1991.2.16.1 is LC 1991.1.2.1.
The standard time of the Lunar Calendar is Beijing (Hong Kong) Standard Time, not GMT. Be sure to adjust appropriately for other time
zones and "Daylight Saving Time".
In the Lunar Calendar, a normal year has 12 months, and a leap year (run-nian) has 13 months, where the extra month is called a "leap
month" (run-yue). For example, the leap month that follows immediately the 6-th lunar month is called the 6-th leap month. A (leap) month
is either a short or long one, which has 29 or 30 days respectively.
There are 10 gan's and 12 zhi's. The ganzhi labeling of the year, month, day and hour of a date is a member of the Cartesian product
GxGxGxG, where G = {1,2,...,60}. For example, "jia-zi" is 1, "yi-chou" is 2, and so on. The ganzhi of the j-th leap month is the same as
that of the j-th month.
The possible options are
b output ganzhi in special "bitmap" characters.
h output hanzi or Chinese characters encoded in (highest-bit-set) GB code.
i convert a lunar date to solar date. The default is to convert a solar date to a lunar date.
l indicate the month is a lunar leap month. This option is meaningful only when the "-i" option is used.
