Example:
March 1993
Modulation:
The carrier amplitude is reduced at the beginning of each
second for the time of 100 ms (binary zero) or 200 ms
(binary one).
Time Code Format:
It consists of 1 minute time frames. A time frame contains
BCD-coded information of year, month, calendar day,
day of the week, hours and minutes. At the switch-over to
the next time frame, the carrier amplitude is reduced for
500 ms duration.
