Okay so in last chapter Gaban wonders how much time has passed since Roger's death and he thinks it's about 3 or 4 years and Shanks corrects him and says it's actually been a decade. Gaban mentions it's probably felt longer for Shanks.
Also at the end of the chapter it's confirmed 45 giant years are 15 human years, exactly ⅓.
If we apply this ⅓ rule to the time Gaban has spent at Elbaph we get 3.33 years, exactly between 3 and 4 years as he mentions.
