• converting the first time and the first date from a first format to a second time in a second format;
• and
• determining whether the data is available based on an indication of whether the data is in use, and a sum of the second time in the second format and a maximum duration of a lockout period for the data.

A computer readable medium storing a program, recorded on the computer readable medium, for converting a first time and a first date in a first format to a second time in a second format, comprising:

• a determining code, recorded on the computer readable medium, executable to determine a number of seconds that have elapsed between a predetermined date and a beginning of a current year of the first date;
• a first adding code, recorded on the computer readable medium, executable to add to the determined number of seconds, a calculated number of seconds calculated from the beginning of the current year to a current month and a current day of the first date to obtain a first sum that varies based on whether the current month is within a leap year and subsequent to a leap day of the leap year;
• and
• a second adding code, recorded on the computer readable medium, executable to add to the first sum, an elapsed number of seconds between a beginning of the current day of the first date and the first time, and a predetermined number of seconds when Daylight Savings Time is in effect, to obtain the second time in the second format.
