If no attribute name is entered when tag configuration is performed to access data in the current database
of a Micro-PWC system, a default attribute name will be provided. Default attribute names are shown in

11.3.3 Format of Time-Stamps
In the historical, historical block, archival and archival block databases, a time stamp is stored with col-
lected data. The time and date, in the format described above, are typically used to define the time period
for which data is to be retrieved.
Time and date stamps recognized and returned by the @aGlance/IT server for the Micro-PWC server are
in the format:
HH:MM:SS DD-MMM-YY
where HH is the number of hours since midnight, MM is the number of minutes, and SS is the number of
seconds. The time is followed by the date (day/month/year). Note that the 24 hour clock is used, and the
month is identified by the first three letters of the month name, in English (i.e., JAN, FEB, MAR, APR, MAY,
JUN, JUL, AUG, SEP, OCT, NOV, DEC).
