Some factors that go into this equation:

Universal Time is 12.7988888888889 in decimal hours.
The Julian date is 2458907.70137257.
The sun’s ecliptic longitude is 339.390020614877 degrees.
Its mean anomaly is 55.051791913 degrees.

These calculations incorporate the switch to the English New Style (N.S.)—i.e., Gregorian— calendar after Wednesday, 02 September 1752; the next day became Thursday, 14 September, skipping eleven days. (Please also note that, while fairly accurate, these calculations remain a bit buggy.)
