Month: 1=January, 2=February,...,12=December.
Day: 1 to 31 in steps of 1.
Last 16 bits are Year (xx/xx/YYYY): 1970 to 2106 in steps of 1.
F052
UR_UINT32 TIME in SR format (alternate format for F050)
First 16 bits are Hours/Minutes (HH:MM:xx.xxx).
Hours: 0=12am, 1=1am,...,12=12pm,...23=11pm.
Minutes: 0 to 59 in steps of 1.
Last 16 bits are Seconds (xx:xx:.SS.SSS): 0=00.000s,
1=00.001,...,59999=59.999s).
