Convert duration string to time value. CurrentTime is used to calculate the days of natural month. If it's set as -1, which means a context free situation, then '1mo' will be thought as 30 days.

Parameters:

duration - represent duration string like: 12d8m9ns, 1y1mo, etc.

Returns:

time in milliseconds, microseconds, or nanoseconds depending on the profile

convertDurationStrToLong

convert duration string to time value.

Parameters:

duration - represent duration string like: 12d8m9ns, 1y1mo, etc.

Returns:

time in milliseconds, microseconds, or nanoseconds depending on the profile
