Tidal variable: <DATE-PROD-PREV.1.mmdd> _1_mmdd_DATE-PROD-PREV
Converts to:
<VARIABLE NAME="%%INPUT_1_mmdd_DATE-PROD-PREV" VALUE="%%$DATE" />
<VARIABLE NAME="%%OFFSET_VALUE_1_mmdd_DATE-PROD-PREV" VALUE="1" />
<VARIABLE NAME="%%RESULT_1_mmdd_DATE-PROD-PREV" VALUE="%%$CALCDATE %%INPUT_1_mmdd_DATE-PROD-PREV -%%OFFSET_VALUE_1_mmdd_DATE-PROD-PREV" />
<VARIABLE NAME="%%YYYY_1_mmdd_DATE-PROD-PREV" VALUE="%%SUBSTR %%RESULT_1_mmdd_DATE-PROD-PREV 1 4" />
<VARIABLE NAME="%%YY_1_mmdd_DATE-PROD-PREV" VALUE="%%SUBSTR %%RESULT_1_mmdd_DATE-PROD-PREV 3 2" />
<VARIABLE NAME="%%MM_1_mmdd_DATE-PROD-PREV" VALUE="%%SUBSTR %%RESULT_1_mmdd_DATE-PROD-PREV 5 2" />
<VARIABLE NAME="%%DD_1_mmdd_DATE-PROD-PREV" VALUE="%%SUBSTR %%RESULT_1_mmdd_DATE-PROD-PREV 7 2" />
<VARIABLE NAME="%%_1_mmdd_DATE-PROD-PREV" VALUE="%%MM_1_mmdd_DATE-PROD-PREV.%%DD_1_mmdd_DATE-PROD-PREV." />
When %%$DATE = 20100908
%%RESULT_1_mmdd_DATE-PROD-PREV = %%$CALCDATE %%INPUT_1_mmdd_DATE-PROD-PREV -%%OFFSET_VALUE_1_mmdd_DATE-PROD-PREV
%%$CALCDATE %%INPUT_1_mmdd_DATE-PROD-PREV -%%OFFSET_VALUE_1_mmdd_DATE-PROD-PREV => %%$CALCDATE %%INPUT_1_mmdd_DATE-PROD-PREV -1
%%$CALCDATE %%INPUT_1_mmdd_DATE-PROD-PREV -1 => %%$CALCDATE 20100908 -1 = 20100907
%%$CALCDATE is an variable function that calculates date offsets in days.
NOTE: the offset value and operator (+ or -) is taken from VARMST_OFFSETS column. The conversion only supports tidal variables with offset of days and operators + or -.
Then %%YYYY_1_mmdd_DATE-PROD-PREV = 2010, %%YY_1_mmdd_DATE-PROD-PREV = 10, %%MM_1_mmdd_DATE-PROD-PREV = 09, %%DD_1_mmdd_DATE-PROD-PREV = 07
Then %%_1_mmdd_DATE-PROD-PREV => %%MM_1_mmdd_DATE-PROD-PREV.%%DD_1_mmdd_DATE-PROD-PREV.
%%MM_1_mmdd_DATE-PROD-PREV.%%DD_1_mmdd_DATE-PROD-PREV. => %%MM_1_mmdd_DATE-PROD-PREV.07
%%MM_1_mmdd_DATE-PROD-PREV.07 => 0907
