Note: MilliTime and MilliTimeSeonds both refer to the same bits on the CAN bus—however they are
decoded twice with a different scale in the DBC file. MilliTime needs to be stored as a signed 64-bit integer
value as the current value already exceeds the limits of a 32-bit integer, however this is not supported by
all CAN software. To overcome that problem MilliTimeSeconds can be stored as a 32-bit double-precision
value, however limitations in the double-precision format mean there may be an error of up to 5 ms and
the resulting decimal numbers may contain rounding errors. Where possible MilliTime should be used,
otherwise use MilliTimeSeconds with care.
