Moscow Time
In e-mail the following format for date and time setting is used:
EDATE::=Day_of_week, Day_of_month Month Year Time Time_zone
Here EDATE is the name of date and time format, the text to the right from ``::=" defines how date and time are written in this format. Below the descriptions of EDATE fields are presented:
Day-of-week
The name of a day of the week. Possible values: MON, TUE, WED, THU, FRI, SAT, SUN. The name is followed by ``," character (a comma).

Set by two or four decimal digits. If a year is set by two decimals it is assumed that this is a number of the year of the XX century. For instance, 74 and 1974 set a year of 1974.
Time
Local time in format hours:minutes:seconds, where hours, minutes and seconds are made up of two decimal digits. The time keeps within the limits from 00:00:00 to 23:59:59.
Time-zone
Offset of local time from Greenwich mean time. It is set by the difference sign ``+" or ``-"and by sequence of four digits. First two digits set the hours and the last two the minutes of offset value. The absolute value of the difference does not exceed 24 hours. Time zone can also be presented by one of the following names:
Name Digital value
UT -0000
GMT -0000
EDT -0400
CDT -0500
MDT -0600

Each two adjacent fields of EDATA are separated with exactly one space. Names of day of the week, month and time zone are written in capitals. For instance, 10 a.m. of the Contest day in St.Petersburg can be presented as
TUE, 03 DEC 96 10:00:00 +0300
