For a server restart, I would suspect that stopping and re-starting will usually take much longer than the usual timespans that are added/subtracted due to synchronization. A favorite contains parameters for connecting to a server. 
The favorite window is shown on launch, but you can always bring it to the front by pressing N.
For a running database engine, the engine seems to protect accordingly. To connect to a PostgreSQL server with Postico, you must first create a favorite. 
An identity column will be filled with a new value generated by the associated sequence. If you are primarily worried over influences of time synchronization, then I would think that this should not be a problem: DEFAULT The corresponding column will be filled with its default value. Given that, I would think that DEFAULT TIMESTAMP does protect a running system against decreasing values but does not guarantee that when the engine (or only the database?) is shutdown in-between.
#Default timestamp postico update
However, when the engine is shutdown and restarted after the system clock has been set to a former time, it will happily use that system time for new DEFAULT TIMESTAMP values. In this case, to update a Postgres timestamp, you need to run a function that automatically sets an updatedat value before any UPDATE operation. Therefore DEFAULT TIMESTAMP may be ahead of the system time. Please pay attention to the short form (data element TIMESTAMP) and long form (data element TIMESTAMPL) as described in the online help. In contrast, SELECT GETDATE() will always return the system time: When the system clock is set back to yesterday, it will display that. beenvisited BOOLEAN DEFAULT false, createdat TIMESTAMP DEFAULT NOW()).
setting the system clock backward (say, to yesterday) makes DEFAULT TIMESTAMP ignore the new (former) value and continue to use the current values - increased as usual by the value of the "default_timestamp_increment" option. With your crendentials handy, use a PostgreSQL client (PGAdmin or Postico are. setting the system clock forward (say, to tomorrow) makes DEFAULT TIMESTAMP use the new (later) value. when using a local database engine and modifying the system clock, it seems that If you use timestamp without time zone, the result of clocktimestamp (), which is a timestamp with time zone, is converted (cast implicitly) to a timestamp without time zone according to the current setting of timezone. To get around you can add/subtract your timezone offset from the date value. So if your server's time is not set to UTC, the date will be offset according to the timezone you are in. Well, according to some tests with 12., the database engine seems to make sure that DEFAULT TIMESTAMP values are increasing monotonically - as long as the database engine is running. Yes, timestamp with time zone, which is an absolute timestamp, would be the correct data type in your case. The default time that geoevent creates is going to be UTC.
