I'm currently setting up a database to populate it with big data. All the data I get comes from Valve's Steam Web API. Therefore, as all timestamps are returned in Unix timestamps, I cannot directly derive the correct timezone - which is also not of any interest as it's to fine-grained for what it is intended for. However, PostgreSQL enables the "length"-value field when setting the column up for timestamp without timezone but I don't know which value is meaningful to enter here and I also couldn't find any information about this value - neither in the official documentation nor on StackExchange so far.
As I'm someone who doesn't set up databases all the time I'm a bit confused and would love to get some assistance. Thanks in advance for your suggestions and input.
