8.1.5 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 character,
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 page 469 for inform-
ation on Format 1S.
