Yes correct. it is then for example:
"ik ging gister" / "ik ga vandaag" / "ik ga morgen" or: "ik zal morgen gaan",
- "ik ga vandaag" you mean than later in the day.
- "ïk zal vandaag gaan" can also, that means also you go later in the day and that is then future time. as a separate sentence: "ik ga" I think it's always present time
