river_time: add_offset

#1 Post by lyzheng » Mon Feb 08, 2010 10:49 pm

Hi,All,

In ROMS CDL file: frc_rivers.cdl, there are lines defined at river_time:
river_time: units="days since 1992-01-01 00:00:00";
river_time: add_offset = 2448623.

Can someone explain the meaning of "2448623"? Thanks.

Zheng
