Heartbeat time syntax

When it is necessary to specify time intervals to Heartbeat, times can be specified as a floating point number followed by an optional units-specifier. The units specifiers allowed are:

  • ms - milliseconds

  • us - microseconds

  • usec - microseconds

If a units specifier is omitted, seconds are assumed. The following are examples of legal Heartbeat time interval specifications:


In spite of the apparent precision inherent in the format described above, in the end, the time given is converted into an integer number of milliseconds.
