Though -tsset- requires integer values, the time variable does not have to
be stored as an integer.
For example:
. set obs 1000000
obs was 0, now 1000000
. gen time = _n
. tsset time
time variable: time, 1 to 1000000
. desc
Contains data
obs: 1,000,000
vars: 1
size: 8,000,000 (74.6% of memory free)
----------------------------------------------------------------------------
storage display value
variable name type format label variable label
----------------------------------------------------------------------------
time float %9.0g
----------------------------------------------------------------------------
Sorted by: time
One possibility would be to create a new time variable:
sort time
gen mytime = _n
tsset mytime
Hope this helps,
Scott
