according to the Python documentation: http://docs.python.org/lib/module-time.html
===snip=== Values 100-1899 are always illegal. . . strptime(string[, format]) . . The default values used to fill in any missing data are: (1900, 1, 1, 0, 0, 0, 0, 1, -1) ===snip=== BTW, check the following code: >>import datetime, time >>print time.gmtime(time.mktime((1900, 1, 1, 0, 0, 0, 0, 1, -1))) (1901, 12, 13, 20, 45, 52, 4, 347, 0) but (1900, 1, 1, 0, 0, 0, 0, 1, -1) is (IMHO) expected.... Hmmm. But I am just a newbie!!! :) Anyway, maybe I am just using a wrong way how to calculate time delta between two time values given in the format "HHMMSS". Does Python provide some other ways how to calculate it? Petr Jakes -- http://mail.python.org/mailman/listinfo/python-list
