3.5.1

Start Time

Start time

is the time a scenario uses for simulation purposes, i.e. the simulated time at which

the scenario begins every time it is run. The

Start time

can be …

a.

a

set time

, as configured for the scenario. Whenever you start this particular scenario,

the previously set

Start time

will be used, e.g. November 4, 2015 at 19:30.

b.

real time

, as derived from the NTP server specified in the Network Configuration, and

triggered by the user pressing

start

, or a SCPI start signal being submitted.

Note:

If NTP real time is used, the scenario start will be delayed by up to

2 minutes, in order to allow for the simulation data to be loaded.

The

Start time

is aligned to the next full GPS minute. The NTP (UTC) timescale is con

verted to the GPS timescale by a UTC-GPS offset defined in the NTP Server settings.

GPS time and leap seconds

The

Start time

is based on GPS time, i.e. the displayed time is always GPS time. Unlike UTC

time – which is frequently displayed by GNSS receivers – GPS time does

not

include leap

seconds.
