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).
-
Day-of-month
- A day of the month. Set by two decimal digits.
- Month
- The name of the month. Possible values: JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC.
- Year
- 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 |
| PDT |
-0700 |
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
Write a program which transforms the given date and time in EDATE format
to the corresponding
date and time in Moscow time zone. So called ``summer time" is not taken
into consideration. Your
program should rely on the predefined correctness of the given
Day-of-week and
Time-zone.
- Moscow time is 3 hours later than Greenwich mean time (time zone +0300)
- Months: January, March, May, July, August, October and December have 31 days. Months:
April, June, September and November have 30 days. February, as a rule, has 28 days, save for
the case of the leap year (29 days).
- A year is a leap year if valid one out of two following conditions:
- its number is divisible by 4 and is not divisible by 100;
- its number is divisible by 400.
For instance, 1996 and 2000 are the leap years, while 1900 and 1997 are not.
Input data file contains date and time in EDATE format in each line.
Minimum permissible year in the input data is 0001, maximum 9998.
Input EDATA string does not contain leading and trailing spaces.
Output must contain a single line for each one in the input file
with date and time of Moscow time zone
in EDATE format. In output EDATE string a Year must be presented
with four decimal digits.
The output string should not include leading and trailing spaces.
