5.4.5 Spectracom Format 1
Format 1 converts the received day of year data (001-366) to a date consisting of day of
week, month, and day of the month. Format 1 also contains a time synchronization status char
acter, year, and time reflecting time zone offset and DST correction when enabled.
Available Formats 1 and 1S are very similar to each other. Most external systems utilizing Data
Format 1 will look for a single-digit day of the month for day 1 through day 9, with a space in
front of each digit ( ^1, ^2, ^3 … 10, 11… ), whereas other systems need to see a two digit
day of the month for all days 1 through 9 with a leading 0 instead of a space (01, 02, 03…
10, 11…).
If your device requires the two digit day of the month for days 1 through 9 (i.e. 01, 02
etc.), select Format 1.
If your device requires the single digit day of the month for days 1 through 9 (i.e. ^1,
^2, etc.), select Format 1S instead. Refer to "Spectracom Format 1S" on page502 for
information on Format 1S.
